title: Figures of a dual-polarized frequency selective rasorber withwide transmission band

description: We proposed a novel and simple dual-polarized frequency-selective rasorber
 (FSR) which has a wide absorption band including a wide transmission
 band. The structure consists of a lossy frequency-selective
 surface (FSS) constructed with metal rings connected by center loaded
 strips as the top layer, and a broad band transmission FSS at the bottom,
 while the two layers are separated by air. To clearly understand how it
 works,  detailed equivalent circuit was derived to accurately
 predict the frequency responses of the structure. To validate our
 proposal, a prototype was fabricated and measured. In this data file,
 simulation results obtained by commercial software Ansys HFSS and
 measurement results are listed. The measured results are in good
 agreements with simulations under normal incidence, which indicates a
 broad absorption bandwidth of 80% that from 3.40 GHz to 8.16 GHz; in the
 meantime, a wide transmission band with an insertion loss of less than
 -1.25 dB is ranging from 9.03 GHz to 12.01 GHz. It should be pointed out
 that, the reflection from the whole structure in the operation band can be
 kept below -10 dB from 4.15 GHz to 11.87 GHz.
description: The simulation results are all obtained through commercial
 software Ansys HFSS. The measurement was carried out in a microwave
 anechoic chamber.
