Power-handling capability of the rhombic waveguide

A dimensionless efficiency factor is used to compute a figure of merit quantifying the power-handling capability of the uniform, perfectly conducting rhombic waveguide. A method involving an infinite sum of nonseparable solutions of the Helmholtz equation provides accurate eigenfunctions and eigenvalues for use in the efficiency factor calculations. The power-handling capability of the rhombic waveguide is compared with that of the standard rectangular waveguide and is found to be only slightly lower.<
