Hybrid FSS Screens for Broadband Microwave Absorber Design at X-Band

Designing the periodic hybrid metal grid/ferrite FSS screens to construct broad-band microwave absorbers is presented in this paper. In practice, the microwave absorbers consist of interleaved metal grid FSS screens and ferrite FSS screen. There are two types of metal grid FSS screens, strip-grating and mesh, to be introduced to obtain a better bandwidth and absorption. The ferrite FSS made of Ba(MnTi)Fe10O19 is used to enhance the performance of absorbers. In the meantime, the decrement method is used to measure reflective response of microwave absorber. Both reflectivity and absorption representations recognize the characterization of microwave absorbers for X-band applications.
