A Wideband Controllable Bandpass Filter Based on Spoof Surface Plasmon Polaritons
Frontiers in Physics, 2022 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 ...

Near millimeter wave bandpass filters [PDF]
Applied Optics, 1981 The properties of bandpass filters for broadband photometry are reported in the 3-12-cm(-1) frequency range. The filters are based on a combination of capacitive grids deposited on thick Mylar substrates and are designed to have very high out-of-band rejection.
