Preparation and Microwave Absorbing Property of Microwave Absorbers with FSS Embedded in Multilayer Composites

摘要

In this paper, we present the experimental results of microwave absorbing materials with a frequency-selective surface (FSS) embedded in the multilayer structural composites. Microwave absorbing materials with the FSS pattern embedded in multilayer structural epoxy resin matrix composites were fabricated. The effects of the FSS on multilayer structural composites for microwave absorbing material design have been investigated. Comparisons were made with the microwave absorptions of the multilayer composites with FSSs of different positions in composites. The microwave absorption properties of the multiplayer composites samples with FSSs are higher than those of the samples without FSSs. The experiment results show that the incorporation of a FSS can effectively change the reflection property of the composite.
