Quasioptical Systems [Hardcover]

Combining a general introduction to Gaussian beams and quasioptical propagation with practical applications, Quasioptical Systems provides a state-of-the-art treatment of the design of low-loss, broadband systems at microwave to submillimeter wavelengths. The approach presented involves utilizing a beam with a Gaussian distribution of field strength perpendicular to its axis, which in turn propagates in a simple, predictable fashion.Preface.
