Abstract:
1. A high frequency radiation transceiver operative in the terahertz regime within a frequency range between 300 GHz and 10 THz, and comprising an electrode's arrangement comprising two or more electrodes including a photocathode electrode and an anode electrode spaced from said photocathode electrode along a cavity axis, said electrodes' arrangement defining first and second portions, the first portion being responsive to an electron flux generated by electron emission from the photocathode and thus being operable as an antenna feeding port causing an electric current flow through the second portion, and the second portion being configured and operable as an antenna radiating portion, responding to said electric current flow therethrough by emission of the high frequency radiation, and responding to an external high frequency radiation signal to effect a change in the electric current therethrough.
