摘要：
In this, a wideband metamaterial absorber for S- and C-band application has been designed. The proposed absorber consists of lumped resistors loadedon Jerusalem cross shaped structure on the upper side of the metal film, which is separated by air spacer on the opposite side of substrate. The complete thickness of the designed absorber is 0.07 lambda(0),where lambda(0) is the lowest absorption frequency. Simulated results exhibited greater than 90% absorptivity in the frequency band from 1.95 - 5.73 GHz with an absorption bandwidth of 98%. The wideband absorption mechanism of the absorber analysed through the electric-field distribution and impedance characteristics.
