Reflection and transmission coefficients measurements for polymer composites with a nano-pzt material using a non-resonant method

Abstract

Abstract The recent significant growth of telecommunications systems, especially in radar applications, has created a sustained need for more smart materials for detecting and/or concealing given objects from radar systems. Key contributing factors in this respect are the reflection and transmission coefficients of such composite materials. The two main methods for calculating the reflection and transmission coefficients are non-resonant and resonant methods. In this work, non-resonant reflection/transmission methods are used to calculate the reflection and transmission coefficients of polymer composites mixed from 1 - 4 wt% of Nano-PZT (Lead Zirconium Titanate). The calculation of the reflection and transmission coefficients is carried out experimentally using an electromagnetic wave on a single layer made from this material. Results show that the transmission coefficient reached a maximum value at 10 GHz, while the reflection coefficient reached a maximum value at 8-9 GHz for all the distance 50-160mm.
