摘要: This paper presents an ultra-thin dual-band polarization-insensitive metamaterial absorber for C-band applications. The proposed structure comprises of a square loop and modified split ring resonator on the top surface metal grounded dielectric substrate. designed offers low profile with thickness λ 0 /56 /49at 5.4 GHz 6.1 GHz, respectively, where is free space wavelength. insensitive towards variations in angle polarization due to symmetrical geometry. It also stable response under oblique incidence both TE TM up 60°. Finally, has been fabricated experimental results are good agreement simulation normal as well incidence.
