Abstract	The problem of optimizing power transmission through uniform perfectly conducting waveguides of double symmetric cross section is discussed. Using an efficiency factor specifically created for single-mode propagation in uniform waveguides, the authors previously developed a unique method of geometric parametrization that determines the waveguide cross-sectional size and shape resulting in maximum power transmission between a source and receiver. Here they use it to analyze the power-handling capabilities of four families of waveguide cross-sectional shapes: rectangular, elliptical, parabolic, and rhombic. Using an efficiency factor based on the two lowest TE modes, it is found that elliptical waveguides can be slightly better than the standard 2:1 rectangular waveguide and that for the four waveguides considered, power-handling is maximized when the second and third TE mode eigenvalues are equal. Good estimates of power-handling capability are obtained by comparison with rectangular shapes or other simple geometries of the same aspect ratio.<>
