A set square design metamaterial absorber for X-band applications

ABSTRACT

This paper presents a set square design which serves as a wideband Metamaterial Absorber (MA) for X-band applications. The simulation results show that the absorber has $-8$ dB absorption bandwidth of 2.51 GHz (8.36–10.87 GHz) and the Full Width Half Maximum (FWHM) bandwidth of 3.55 GHz (7.47–11.02 GHz). MA proposed in this paper uses $F{R}_4$ as a substrate having thickness of 1.6 mm and overall dimensions of 10 mm × 10 mm with center frequency at 9.61 GHz. The absorption mechanism which depends on effective permittivity (${ϵ}_{\mathrm{e}\mathrm{f}\mathrm{f}}$) and effective permeability (${\mu }_{\mathrm{e}\mathrm{f}\mathrm{f}}$) is explained and plotted.
