THE REFLECTING BEAM WAVEGUIDE,
Abstract
A type of beam waveguide which uses appropriately shaped metal reflectors instead of dielectric lenses as the phase correcting devices is described. A theory has been developed which, subject to certain restrictions, describes the modes of this type of beam waveguide and predicts a loss of the order of 0.01 db per iteration. A reflecting beam waveguide comprising eight aluminum reflectors has been investigated at a wavelength of 4 millimeters. The measured loss per iteration is approximately 0.015 db which is in good agreement with the theoretical value. The cross sectional electric field distribution has also been measured and found to be in satisfactory agreement with the theory. A convenient and inexpensive technique for constructing the reflectors from commercially available metal foils is described. It is shown that the reflecting beam waveguide is a practical system for the transmission of power at submillimeter wavelengths. (Author)
