A Dual Grating Waveguide Structure for Wakefield Acceleration at THz
By
Progress In Electromagnetics Research M, Vol. 36, 47-56, 2014
Abstract
A dual grating waveguide accelerator structure is investigated and compared with the dielectric wakefield accelerator at THz frequencies. In a dielectric wakefield accelerator, thinner liners for a given current and liners having lower dielectric constant are not preferable due to the fact that they generate much lower axial wakefields. This limits the operation of the device at THz. On the other hand, it is shown that a grating waveguide is tuned at THz with shallower slot heights with competitive wakefield gradients than a dielectric wakefield accelerator.
