Abstract

The design and experimental evaluation of microwave absorbers with frequency selective surface (FSS) embedded in impedance-graded carbon fiber (CF) composite is presented. Samples with different FSS patterns embedded in CF composites are fabricated and experiments carried out to find out the effects of embedded FSSs. It is found that both the FSS pattern and its location in the composite are critical for the reflection property of the sample. The results were compared with that the theoretical predictions using a micro-genetic algorithm (MGA) and are in good agreement.
