A Novel Multilayer Structure with Frequency Selected Surface for Electromagnetic Compatibility

Article Preview

Abstract:

Electromagnetic wave absorbers can be widely used in Electromagnetic Compatibility (EMC). We proposed a novel multilayer structure of metal alloy-ferrite-plastic composites. A new structure with Frequency Selected Surface (FSS), which has filter characteristic, embedded in the composites was fabricated to improve the absorption performance. In bandwidth of 8.04GHz, the reflectivity was smaller than-8dB and the thickness was only 2.6mm. The reflectivity was measured using a standard NRL Arch technique in a frequency range of 3-18 GHz. The experimental results indicate that it is possible to make a desirable thin, broadband EMW absorber by the incorporation of an FSS into the magnetic absorbing materials.
