Electron Beams from Needle Photocathodes and a New Theory of the Smith-Purcell Free-Electron Laser

A promising source of radiation in the important terahertz (THz) region of the spectrum is the Smith-Purcell free-electron laser (SPFEL). This dissertation presents a new theory of the SPFEL, taking into account dispersion of evanescent surface waves on the grating. From the dispersion relation for...
