“…The frequency selective surface (FSS), a kind of 2D/3D periodic structure, has been extensively investigated in last decades 1‐3 . Due to its unique frequency filtering characteristics, they are widely applied in a variety of important applications, such as stealth radomes, 4 reduction for radar cross section (RCS), 5 absorbers, 6,7 and applications in shielding 8,9 …”

A frequency selective rasorber (FSR) with fast roll‐off and wide absorption/transmission band is introduced in this article, working as a band‐pass filter from 1.7 to 3.1 GHz, while working as an absorber from 5.72 to 17 GHz. The proposed FSR is designed by the lossy layer at the top and the band‐pass frequency selective surface (FSS) at the bottom. The lossy layer is constructed by two parts including a square loop and a series RLC structures to provide a wide absorption band. The band‐pass FSS is a three‐tier structure including two patch layers and one meander line layer in the middle. This multilayer FSS is used to generate a transmission window in S band and a wide reflection band in the high frequency. The working mechanism of the FSR is explained by the equivalent circuit model. Finally, the fabricated prototype and the measurement results are presented to verify the design of the FSR.
