Abstract
A transmission line is disclosed which comprises a conductive layer, a resistive semiconductor layer disposed on the conductive layer and a blocking electrode disposed on the resistive semiconductor layer. By applying a biasing voltage between the blocking electrode and the conductive layer, a depletion layer is produced in the resistive semiconductor layer, the depletion layer formed in the semiconductor layer being used as a medium for transmission of electromagnetic wave.
