| Abstract | Spoof surface plasmon polaritons (SSPPs) have been developed rapidly because of the advantages of strong field constraints, low inter-channel cross talk, and low loss. However, the functions of plasmonic devices made of traditional passive SSPPs are completely fixed and cannot reach reconfigurable capability once the devices are fabricated. For the current development status, it is an urgent issue to design a reconfigurable device to control SPP waves dynamically in real time. This paper proposes a dynamic reconfigurable bandstop filter by using the concept of programmable SSPPs. The filter has a significant regulation function in the wideband range from 4 GHz to 22 GHz. The center frequency, number, and bandwidth of the stop band can be reconstructed in real time by programming the bias voltage, and the transmission coefficient ( |
