Abstract [en]

In this work, the concept of a solid-state amplifier based on the slow-wave interaction with drifting electron flow in a metal periodic structure is proposed for application in the low THz frequency range. Results of calculations at 330 GHz show the linear gain up to 50 dB/cm, including ohmic losses in the metal.
