Microwave Absorber with Optimized and Perforated Matching Layer for Double Layer Resistive- FSS
In this paper a modified ultra-wideband microwave absorber is proposed in the form of double layer resistive FSS with perforated matched layer, the proposed design results shows an absorption bandwidth of 40.1 GHz in the range between 4.8 to 45.9 GHz under −10 dB at the unit cell level with fractional bandwidth(FBW) of 162.13 % with a total thickness of 7.1mm that is 0.113λl at the lowest cut-off frequency. Moreover, the proposed design shows stability at different inclination angles up to 80 degrees for TE-mode. Further, a radar cross section (RCS) study is proposed for 10x10 array versus prefect electric conductor (PEC) and the results shows a high absorption level at different frequencies
