Abstract

The goal of this study is to investigate the properties of barium hexaferrite and iron sand as microwave absorbers. The focus is on understanding how these materials affect microwave absorption and the specific frequency range of waves they produce. The solid reaction method was used in the study. The study's findings indicate that the combination of iron sand with barium hexaferrite material leads to the formation of a homogeneous material with a single phase. X-ray diffraction pattern data confirms the presence of a single-phase material, specifically iron sand and barium hexaferrite, which consists of hematite and barium hexaferrite. The VNA observations reveal that the iron sand and barium hexapherite materials can absorb electromagnetic waves at a radar wave frequency of 11.1 GHz, resulting in a loss of -23.86 dB. Furthermore, the material demonstrates its ability to absorb microwaves. The absorption of microwaves relies on the quantity of particles in the absorbent substance and its microwave-absorbing capacity. To thoroughly assess the absorption properties of various samples, it is essential to not only evaluate their reflection loss but also analyze how well they operate as microwave absorbers.

Abstract

We have carried out a thorough investigation to scrutinize the characteristics of iron sand and nickel oxidizer, focusing on their crystal structure as microwave-absorbing materials. The study investigates the impact of these materials on microwave absorption characteristics and the frequency range of the resulting waves. The solid-state reaction method is used in the research methodology. The research findings indicate that the combination of iron sand and nickel oxide leads to the formation of a homogeneous substance. The X-ray diffraction pattern data reveals the presence of two single-phase materials: iron sand, which consists of hematite, and nickel oxide. The iron sand and nickel oxide materials underwent characterization using EDS, revealing a composition that closely approximated stoichiometry. A Vector Network Analyzer (VNA) test shows that the iron sand and barium hexaferrite mix may be able to effectively absorb electromagnetic waves at a radar frequency of 12 GHz, leading to a -24 decibels (dB) drop.
