Analytical and Computer-Aided study of Pyramidal Microwave Absorber

Abstract

There are many conditions that affect the performance of absorbent microwave pyramidal shape, which must be taken into account when using it as an essential component in the design of the Anechoic Champers, and these factors are: position the gate are placed, at the gate area, incident angles of electromagnetic wave to the microwave pyramidal absorber, the distance between the gate and the microwave pyramidal absorber. It will be shown who these conditions impact of these cases on the performance by studying the reflection coefficient S₁₁. This will be implemented by means of computer simulations carried out by the program CSTMWS and using fixed-isolating material which has permeability coefficient .

It is worth to note that the microwave pyramidal absorber designed to operate effectively within the frequency range of (1 ÷ 20) GHz.
