Abstract

A design for a planar relativistic surface wave generator operating in the G-band has been developed through theoretical analysis and three-dimensional particle-in-cell modeling. The device is based on a sheet electron beam produced by the SINUKI accelerator (600 keV/1 kA/17 ns, Institute of Applied Physics, Russian Academy of Sciences) using explosive electron emission. The electrodynamic system of the generator employs a two-dimensionally periodic slow-wave structure that implements a two-dimensional distributed feedback mechanism and enables mode selection across the transverse spatial coordinates. The simulation demonstrates the feasibility of stable single-mode generation in this configuration, achieving an efficiency of approximately 8% with an oversize factor (defined as the ratio of system width to wavelength) of about 15. Experimental results confirm a stable single-mode generation regime at 160 GHz, with pulse durations of up to 5 ns and output power reaching approximately 30 MW.
