Keywords： high power microwave

Backward wave oscillators (BWOs) driven by intense relativistic electron beams are very efficient means of producing high-power microwaves.However,the efficiency of conventional BWO is lower than 30％.An X-band oversized BWO with non-uniform slow wave structure is designed to improve RF output characteristics.In particle-in-cell simulation,a high power microwave with a power of 8.0 GW and efficiency of 40％ is obtained,compared with that of 30％ obtained in a conventional relativistic BWO.
