Abstract :
We demonstrated electronically switchable extraordinary terahertz transmission through sub-wavelength metallic hole arrays fabricated on doped semiconductor substrates. A reverse voltage bias results in a controllable depletion thus tuning the substrate loss and switching the transmission.
