摘要	To obtain a frequency-selective surface (FSS) structure with band-pass and band-stop spatial filtering functions at low frequency in different time domains, a design method for switching between band-pass and band-stop responses of the FSS was proposed. It was consisted of mounting PIN diodes on the miniaturized FSS, which was designed based on a convolution technique, and utilizing EM/Circuit Co-Simulation for calculations and analysis. It was noteworthy that the convoluted pattern was not only the filtering structure, but also serves as the feeder. When PIN diodes were in the ON-state, the parallel LC circuit constituted by the inductance L1of the metallic patches and the capacitance C1of the pattern slots represents the band-pass performance of the FSS. Conversely, the total capacitance C2of the reversed PIN diodes and the gap between the pads in series with the inductance L2of the metallic patches indicate the occurrence of band-stop performance for the FSS when the PIN diodes are in the OFF-state. Using a printed circuit board and surface mounting technology, a prototype of 400 mm400 mm was fabricated and measured by the free space method. The simulation and test results indicate that, for a frequency of 2.45 GHz, the FSS exhibits strong transmission when the PIN diodes are in the ON-state, whereas a strong reflection is obtained when the PIN diodes are in the OFF-state. With this method, arbitrary switching of the FSS between band-pass and band-stop responses is realized, based on electrically controlled PIN diodes, which has a broad range of prospective applications in the fields of telecommunication, electromagnetic shielding, and radar stealth. 2018, Science Press.
