Abstract

Optical fiber is a medium that spreads information in the form of light waves. The quality of the optical fiber can be determined by knowing the dispersion value of the polarization mode which is one of the characteristics of the optical fiber by using a single-mode optical fiber design simulation method using the OptiFiber software. The single-mode optical fibers used in the simulation are SMF-28, SMF-28e, SMF-28e+, SMF-28e+ LL, SMF-28 ULL. A good quality SMF for long-distance communication is an SMF that has a small PMD value.

Abstract

Terahertz radiation (THz) has interesting and effective properties in the field of biomedical imaging techniques, this is because of its ability to interact easily, is not ionized, and does not damage biological tissue. The purpose of this study was to determine the effect of THz radiation power density on temperature distribution and heat production in bovine biological tissue consisting of skin, fat, and muscle using a modeling approach. This study uses biophysical computation techniques with the Simulink-MATLAB model in the 0.1 – 1 THz frequency range, 50 – 150 mW power, and 5 – 25 mW/mm3 power density. Temperature distribution modeling is carried out in two ways, namely with different power densities and variations in the circumference of the THz radiation source. The results showed that the higher the power density used, the greater the absorbed radiation energy with increasing temperature. This causes the temperature distribution in the biological tissue to be wider and the production of heat in the tissue will increase. The results of imaging analysis of temperature distribution to depth in bovine biological tissue, show that fat tissue has less heat production compared to other tissues. The comparison of experimental data and modeling results shows an error percentage of 1.09%.

Abstract

The acceleration of the growth in the rate of oil palm seed roots is a non-chemical solution in nursery needs. Utilizing the electricity sector as an increase in germination productivity. In this case, this study examines variations in the electric field direct current 50, 100, 200, 400, 800, and 1000 V/m and the exposure of time 15, 30, 45, and 60 minutes. The results showed exposure to an electric field direct current in voltage of 100 V/m increased germination at each exposure time by 17%, 21%, 20% and 26% with exposure times of 15, 30, 45, and 60 minutes to control. However, a maximum intensity of 1000 V/m inhibits the germination process for each time of 30, 45, and 60 minutes by 8%, 9%, and 12% in the control. Exposure to direct current in electric field intensity and exposure of time affect root metabolism in the germination process.

Abstract

FBG is widely developed as a sensor in its application as a sensor, FBG is commonly used either in industry or in clinical applications to measure changes in physical parameters such as pressure, strain, temperature, and corrosion, as well as to monitor the body's heartbeat and breathing. This research uses 2 types of FBG, namely uniform and chirping. The spectrum used is in the range of 1550 nm. Using an optical sensing interrogator as a tool to read wavelength changes as well as input and output with an infrared laser light source. This study aims to analyze the response of FBG sensors to human voice vibrations with variations in the intensity of sound violence. The results showed that at a hardness intensity of 60 dB using a uniform FBG with a reflectivity of 10% experienced a wavelength change of -0.0304 nm, at an intensity of 70 dB 0.0304 nm, and an intensity of 80 dB experienced many wavelength changes 0.06669 nm. The greater the intensity of the sound, the more FBG response shows an increase in wavelength. The largest strain value detected by the uniform FBG with 10% reflectivity is at 70 dB intensity of 5.5579 × 10-5 strain while the lowest value is at 80 dB intensity of 4.4816 × 10-5 strain. The chirping FBG with 10% reflectivity has the highest strain value at 70 dB intensity with a respective strain value of 1.18 × 10-4 strain. Giving sound vibrations such as some of A, I, U, E, and O to FBG is useful for calculating how the transmission peak of FBG shifts due to strain. When the object emits sound vibrations with a certain intensity, the pressure that occurs will be more than the object when it is at rest, so the greater the sound vibration, the greater the strain that occurs.

Abstract

This study aims to observe the ability of a thin layer of zinc oxide (ZnO) which is applied to sensor technology. Currently, the low detection limit of the sensor is a problem in its use. Metamaterials offer resonant properties in increasing sensitivity, but their performance is still below the current high modern technology. The high engineering properties of metamaterials provide opportunities for realizing renewable metamaterials. ZnO thin layer semiconductor material as a transparent conductive oxide can provide a wide detection potential. The ability of ZnO thin films to be adapted to metamaterial sensors can be further investigated and improved for the future.

Abstract

Intravenous (IV) infusion therapy is a medical procedure that involves the insertion of fluids directly into the patient's vein using a needle/cannula. Mismanagement during infusion fluids replacement due to negligence and shortage of medical personnel and human error must be addressed promptly. Increasing in numbers of patients throughout the Covid-19 pandemic has raised the use of infusion and the error percentage in manual infusion monitoring has also escalated, as consequence, the needs of automatic-handy tools with affordable price become a concern. The infusion monitoring system used consists of three parts, namely sensing and computing, communication, and User. This device allows monitoring and visualization of IV therapy infusion for each patient in real-time, at a remote location.

Abstract

Non-thermal Argon plasmas serve multiple functions, particularly in healthcare and industrial applications. Numerous particles of the same species exhibit varying velocities, referred to as a 'population'. The distribution function is a standard method for characterizing a population. The speed and energy distribution functions in the Maxwell-Boltzmann equation are simulated utilizing MATLAB. The density of each species was numerically calculated using the Runge-Kutta method. This research reviews various Argon species, including Ar*, Ar+, Ar(1s5), Ar(1s4), Ar(1s3), Ar(1s2), Ar, and electrons. The parameters utilized include a pressure of 10 mTorr, an Argon temperature about 400 K, and an electron temperature about 30,000 K. The maximum velocity probability density value is observed in the Ar+ species at 6.18 x 107 (m/s)-1, while the minimum value is found in electrons at 1.93 (m/s)-1. The maximum energy probability density value is observed in the Ar+ species at 2.13 x 1029 (Joule)-1, while the minimum value is found in the Ar(1s3) species at 1.40 x 1025 (Joule)-1. The time evolution of the distribution function, independent of the coordinates r, is associated with v, at t = 10-8 s. The velocity distribution function is significantly affected by the density value, while the distribution function is contingent upon the velocity.

Abstract

Local thermodynamic equilibrium is a foundational concept in plasma physics and heat transfer, describing a state where each small region of a system can be treated as if it is in thermodynamic equilibrium, even if the whole system is not. However, achieving accurately perfect thermodynamic equilibrium conditions in real-experiments is often challenging. It often struggles for understanding phenomena like excited states or specific Arrhenius-driven reactions. As a result, the advantages of plasma modeling with simplifications can sometimes overshadow the disadvantages of experiments. This study simulated the ionization process of argon plasma using the 4th order Runge-Kutta numerical method. The simulation, initiated with initial densities before the simulation is run, each of them is electrons 2.6 × 1018 m-3, neutral argon (Ar) 2.6 × 1018 m-3, positive argon ions (Ar+) 2.6 × 1018 m-3, and positive diatomic argon ions (Ar2+) 2.6 × 1018 m-3, successfully obtained reaction rate equilibrium data at the 625th iteration. The final densities observed were 2.46 × 1018 m-3 for electrons, 2.27 × 1018 m-3 for neutral argon, 6.4 × 1015 m-3 for Ar+, and 4.34 × 1017 m-3 for Ar2+. These results show the equilibrium reaction rate in argon plasma which provides information that density of electron and Ar+ species show a decreasing trend while density of Ar and Ar2+ species shows an increasing trend which are the result of ionization and recombination processes in the entire plasma system.

Abstract

Optical fiber is an advanced transmission medium composed of glass fibers, offering significantly higher data transfer speeds compared to conventional electrical cables. This study aims to analyze power loss resulting from bending in single-mode optical fibers (SMF) to assess the impact on optical signal quality. Five distinct SMF types were simulated using OptiFiber software at wavelengths of 1310 nm and 1550 nm, with bending radii varying from 20 – 46 mm in increments of 2 mm. The results demonstrate that power attenuation in optical fibers is affected by the wavelength of operation and bend radius. At a wavelength of 1310 nm, the highest material loss was recorded in SMF-28 at 0.0125 dB/km, whereas at 1550 nm, SMF-28 exhibited the highest material loss of 31.963 dB/km. Moreover, an increase in bending radius results in a reduction of bending losses, while a decrease in bending radius leads to a significant increase in losses. These insights contribute to the development of improved fiber optic cable designs by advocating the use of enhanced protective shielding to mitigate bending-induced signal degradation.

Abstract

The continuous advancement in wireless biomedical technology necessitates the development of compact, high-performance antennas capable of operating across a wide frequency range. In this context, this study reports the design and optimization of a square split-ring resonator (SRR) metamaterial-based microstrip antenna to enhance bandwidth and gain characteristics for wideband biomedical sensing. The proposed metamaterial, composed of one to four square SRR unit cells, was modeled using copper patches on an FR-4 substrate with a dielectric constant of 4.3 and simulated in CST Studio Suite 2019 over a frequency range of 0.009 – 9 GHz. The electromagnetic behavior of the structure was analyzed through S-parameter characterization, and the Nicolson–Ross–Weir (NRW) retrieval method was applied to extract the effective constitutive parameters, including relative permittivity, relative permeability, and refractive index. The optimized four-cell SRR configuration demonstrated double-negative (DNG) characteristics, exhibiting a relative permittivity of -153.65, a relative permeability of -8.85, and a refractive index of -9.48, thereby confirming the negative-index properties essential for enhanced electromagnetic field confinement and energy concentration. Integration of the optimized metamaterial into the microstrip antenna structure yielded significant performance improvement, achieving a return loss of -48.31 dB, bandwidth of 4.37 GHz, and gain of 2.23 dBi. These results substantiate that the square SRR metamaterial contributes to superior impedance matching and field localization, making the proposed antenna architecture highly promising for wideband biomedical sensing and potential internet of things (IoT) healthcare implementations.
