A Wideband Controllable Bandpass Filter Based on Spoof Surface Plasmon Polaritons
A wideband controllable band-pass filter is proposed, which is based on the spoof surface plasmon polaritons (SSPP) and slip ring resonators (SRR). The design concept of the bandpass filter is using the SSPP and SRR to control the high cut-off frequency and filter the low-frequency wave, respectivel...
