Wakefield Acceleration in a Dual-Grating Waveguide

The wakefield acceleration in a dual grating waveguide slow wave structure (DGWSWS) is proposed. Analytical expression of the wakefield amplitude and frequency is calculated. The wakefield amplitude is analyzed in terms of the grating waveguide parameters, i.e., grating width and grating slot height...

Description
Summary:The wakefield acceleration in a dual grating waveguide slow wave structure (DGWSWS) is proposed. Analytical expression of the wakefield amplitude and frequency is calculated. The wakefield amplitude is analyzed in terms of the grating waveguide parameters, i.e., grating width and grating slot height. The results indicate that the grating wakefield accelerators with shallower slots can operate at terahertz with competitive accelerating gradients when compared with a dielectric wakefield accelerator.
