ABSTRACT
Initially, a design study is presented for a W-band planar coupled-cavity backward wave oscillator at 94.5 GHz. It is numerically simulated using CST particle-in-cell (PIC)-3D simulator and same design validated with another PIC-3D code. Further, output powers of several BWOs combines in a typical manner which resulted power multiplication order of 2.5 times and electronic efficiency multiplication almost order of 1.25 times. The in-depth particle-in-cell simulations were performed for proving the proposed novel concept.
