Dispersion characteristics of dielectric loaded grating for Smith-Purcell radiation in three dimensions

A novel type of slow-wave structure for Smith-Purcell device called dielectric loaded metal grating, is proposed in this article. The three-dimensional (3D) analytical theory for the “hot” dispersion relation is derived using the field matched method and the results accord well with the simulation data performed by using 3D particle-in-cell (PIC) code.
