摘要

A W-band extended interaction oscillator (EIO) operating at two different types of 2 pi modes is presented. The modes and output characteristics were studied, and the circuit was optimized to ensure similar and efficient outputs of two standing- wave modes. For a cylindrical electron beam radius of 0.2 mm, voltage of 14 kV, and current of 0.5 A, particle-in-cell simulation predicts 616 W at 93.76 GHz for the 2 pi gap mode and 367 W at 94.22 GHz for the 2 pi cavity mode. In this paper, numerical simulations demonstrate the ability of the EIO circuit to be operated with two standing wave modes in the millimeter-wave range.
