Diffraction Effects in Directed Radiation Beams
Abstract
A number of proposed applications of electromagnetic waves require that the radiation beam maintain a high intensity over an appreciable propagation distance. These applications include, among others, power beaming, advanced radar, laser acceleration of particles and directed-energy sources. The quest to achieve these objectives has led to a resurgence of research on diffraction theory. This report presents a survey and critique of the analyses and experimental tests of solutions of the wave equation in connection with so- called diffractionless and other directed radiation beams. The examples discussed in this paper include electromagnetic missiles, Bessel beams, electromagnetic directed energy pulse trains, and electromagnetic bullets. Electromagnetic wave propagation.
