Theoretical and Experimental Study on Transparent Wave Absorber Using Resistive-Film for TE and TM Polarizations at X-Band

In this paper, the theoretical and experimental examinations of a transparent wave absorber is carried out so as to realize the large absorption under TE and TM wave polarizations in X-band. The wave absorber is analyzed on the basic of an equivalent circuit using a distributed line. The proposed wave absorber is made of Glass and PC(Polycarbonate) plate which is deposited with ITO(Indium Tin Oxide). The calculation model is partly fabricated by the glass(glass-glass-glass) or PC(PC-glass-glass) for the surface of the absorber. The design charts including the variation of thickness and complex permittivity of used materials are also provided. It has been confirmed that the transparent wave absorber for TE and TM polarization waves is realized.
