Bragg Deflectors of Wave Fluxes for High-Power Relativistic Masers
- 1 Downloads
Quasi-optical Bragg structures that represent sections of planar waveguides with tilted (with respect to the beam propagation direction) corrugation are studied. It is shown that such structures may serve as efficient deflectors for high-power wave fluxes and, hence, can be used for separation of microwave radiation and electron beam in relativistic masers. The corrugation configuration is optimized to increase the efficiency of transformation of wave fluxes to the transverse direction and improve uniformity of the spatial distribution of scattered radiation. The simulated results are verified using cold electrodynamic tests.
