摘要：

We propose dynamic control to excite spoof surface plasmon polaritons (SPPs) in the microwave frequency. Using switchable devices, the excitation of spoof SPPs can be turned on and off depending on the DC voltages applied on the switchable devices. To demonstrate the dynamic mechanism, a switchable spoof SPP waveguide is proposed and fabricated in the microwave frequency. Both simulation and measurement results show good performances of the dynamic control in exciting spoof SPPs. (C) 2014 AIP Publishing LLC.
