A design methodology is presented for utilizing electromagnetic bandgap metamaterials, also known as artificial magnetic conductors, to realize ultra-thin absorbers. One approach that has recently been proposed is to place a resistive sheet in close proximity to a frequency-selective surface acting as an artificial magnetic conductor. However, we demonstrate in this paper that incorporating the...

Frequency selective surfaces (FSSs) play an important role in wireless systems as these can be used filters, isolating the unwanted radiation, microstrip patch antennas for improving performance of and other 5G applications. The analysis design double concentric ring frequency surface (DCRFSS) is presented this research. In sub-6 GHz FR1 spectrum, a computational synthesis technique creating DC...

The low RCS level out of operating band is urgent for radome while keeping its communication window. To solve this problem, we propose a frequency selective rasorber (FSR) that exhibits pass-band between two absorption bands in paper. surface currents on finite metallic wire media analyzed firstly to elaborate transverse standing waves mechanism. High-efficiency and broadband can be achieved by...
