This book deals with diffraction radiation, which implies the boundary
problems of electromagnetic radiation theory. Diffraction radiation is
generated when a charged particle moves near a target edge at a distance
( - Lorentz factor, - wave length). Diffraction radiation of
non-relativistic particles is widely used to design intense emitters in
the cm wavelength range. Diffraction radiation from relativistic charged
particles is important for noninvasive beam diagnostics and design of
free electron lasers based on Smith-Purcell radiation which is
diffraction radiation from periodic structures. Different analytical
models of diffraction radiation and results of recent experimental
studies are presented in this book. The book may also serve as guide to
classical electrodynamics applications in beam physics and
electrodynamics. It can be of great use for young researchers to develop
skills and for experienced scientists to obtain new results.
