Abstract :
We present a terahertz modulation scheme which employs reconfigurable metallic slits to achieve higher modulation depth and higher modulation bandwidth compared to the state-of-the art. The initial theoretical and experimental results promise feasibility of a terahertz modulation depth of more than 4.5 over a broad modulation bandwidth of 2THz.
