Abstract:

Research is presented on the diffraction of an electromagnetic evanescent wave by an infinitely conducting half plane and by an infinitely conducting cylinder of circular cross section. General formulas are given for the near and far fields. Scattering patterns are shown in several particular cases. This study is intended as a first step toward finding the best grating structure which makes it possible to abstract the greatest amount of energy, at a prescribed frequency, from a beam of charged particles in uniform straight motion.
