Microwave frequency conversion using a spoof surface plasmon polariton waveguide integrated with split-ring resonators and micro-electromechanical resonator arrays
We experimentally demonstrate frequency conversion based on a spoof-surface plasmon-polariton waveguide and microbridge resonator arrays integrated into the gap of a split-ring resonator array capacitively coupled to the waveguide. Frequency conversion was achieved by mixing the microwave carrier frequency with a modul...
