abstract = "This letter proposes a wide transmission band frequency-selective rasorber (FSR) which has a lower absorption band and higher reflection band. The FSR consists of a resistive sheet and a bandpass frequency-selective surface (FSS). Under simple guideline of equivalent circuit model (ECM), a wide-transparent window can be achieved through cascading three interdigital resonator. Lumped resistors are loaded at the corner of resistive sheet to absorb the incident wave at lower band. When the resistive sheet is in series resonance, the incident wave is nearly reflected. The simulation results indicate that a -3 dB transmission window can be obtained from 7.9 GHz to 12.2 GHz while a 90\% absorption band is from 3.4 GHz to 7.2 GHz and a -1 dB reflection band is from 13GHz to 16GHz.",
