摘要：
This article designs a frequency selective rasorber (FSR) with switchable transmission and reflection bands, and the switchable function is achieved by loading PIN diodes on the bandpass frequency selective surface (FSS). The overall structure of the switchable frequency selective rasorber (SFSR) consists of a cascaded 2-D lossy FSS and a lossless FSS. When the diode's state transitions from OFF to ON, the passband could switches from lower frequency to higher frequency. In full wave simulation, FSR exhibits frequency response that there is a transmission band and a reflection band near the two absorption bands, and the transmission band is located at the low frequency and the reflection band is located at the high frequency in the OFF state, with frequency ranges of 4.05-4.34 GHz and 5.81-6.03 GHz, respectively. In the ON state, the transmission band switches to high frequency and the reflection band switches to low frequency, with frequency ranges of 4.08-4.43 and 6.00-6.11 GHz, respectively.
