Abstract

In this paper, a data processing technique to obtain the true characteristic of microwave absorber material characterization is proposed. This technique addressed to overcome the limitations of port extension is known as hybrid de-embedding technique, which in principle is carried out by combining the structure model data of test fixture that is used with simulated data or experimental measurements. In this technique, the test fixture is simulated numerically to get S (scattering) parameter data. Then the S parameter is converted into the T parameter (transfer) to be used for de-embedding process by removing the characteristic of test fixture used so that the true characteristics of a microwave absorber material can be revealed. To verify the accuracy of technique proposed, the characteristics of a microwave absorber is simulated numerically and measured experimentally. The simulation and measurements results are then processed using the proposed technique to be compared with its ideal model. In general, the result of de-embedding process shows that the proposed technique has high accuracy.

Abstract

The tracking of vehicles using RFID was developed consider three major problems, i.e. traffic signal timing, congestion on road and theft of vehicles. This paper describes an algorithm for predicting the speed of traffic light violators. The novel algorithm is implemented in the form of a simulation program. The traffic light system is equipped RFID reader as the main tool for identifying the vehicle’s RFID tags. In the simulation, the vehicle’s ID is generated using a random number generation. The distribution of the vehicle’s numbers is uniform and the expected number of vehicles violated the traffic light is not more than 3 % of the total number generated. The timing accuracy for speed traffic lights violator is 100 milli seconds. From the simulation conducted, the algorithm has performed as expected. It is able to predict the speed of traffic light violators ranging from 5 km/h up to 80 km/h in real-time.
