Spoof surface plasmon polaritons based tunable band notch filter for terahertz and microwave

A novel tunable band notch filter which consists of a coplanar waveguide and a corrugated metallic strip with horn shaped arms is presented for terahertz (THz) and microwave applications. The corrugated metallic strip with horn shaped arms offer more attenuation to EM wave than the corrugated metallic strip with conventional rectangular arms as the horn… (More)
