摘要：

Design and analysis of ultrathin wideband non-transparent, semi-transparent and optically transparent microwave metamaterial absorbers have been reported in this article. Non-transparent absorber composed of FR4 dielectric substrate has been fabricated and experimentally verified. Transparent and semi-transparent absorbers are developed by utilizing AgHT-8 conducting sheet and copper sheet, respectively. Both the absorbers are analyzed and compared for different substrates, viz. glass and PET. The FWHM bandwidth of about 25.8% has been observed for non-transparent absorber which is ranging from 2.14 GHz to 2.77 GHz. Under normal incidence, simulated -10dB absorption bandwidth of about 17.3% has been attained from 2.223 GHz to 2.645 GHz covering S-band frequencies. Standard printed circuit board technique is utilized for fabrication and the absorber prototype is verified by waveguide measurement method. The measured and simulated results are in agreement. The proposed non-transparent absorber has ultrathin thickness of lambda(0)/40 and is compact with cell size of 0.21 lambda(0) at the lower absorption frequency of 2.28 GHz.
