Paper Abstract

The properties of highly oversized tubular HE11 waveguide (circumferentially corrugated or dielectrically lined metal guide) and of quasi-optical Gaussian beam waveguide (using focusing metallic mirrors) are reviewed and compared in order to extract the specific advantages and disadvantages of these two approaches for use in low-loss megawatt CW millimeter-wave transmission systems. Manufacturing imperfections may limit the application of the convenient HE11 waveguide to the 1 MW / 100 to 140 GHz range. Quasi-optical transmission is ideal for multi-megawatt millimeter- and submillimeter-wave systems using beam combination. Depending on the power and frequency requirements and on the accessibility constrains, combined systems may be realized.
