An X-band metamaterial slow-wave structure (MTM SWS) has been suggested in which leverages the reverse Cherenkov radiation property of metamaterials to function as a backward wave oscillator (BWO). The proposed MSWS helps in device miniaturization and intense electron bunching. An X-band MTM BWO with complementary electric split ring resonators (CeSRRs) integrated inside a circular waveguide makes up the electron-beam structure.

摘要

An X-band metamaterial slow-wave structure (MTM SWS) has been suggested in which leverages the reverse Cherenkov radiation property of metamaterials to function as a backward wave oscillator (BWO). The proposed MSWS helps in device miniaturization and intense electron bunching. An X-band MTM BWO with complementary electric split ring resonators (CeSRRs) integrated inside a circular waveguide makes up the electron-beam structure. The cold test simulation is performed to determine dispersion and coupling impedance properties. The transmission and reflection coefficients of the proposed MSWS are also evaluated.
