title: Waveguide losses in sharply bent circular hollow waveguides.
abstract: Losses in the general class of sharply bent circular hollow waveguides are evaluated theoretically for linearly polarized modes. A theory presented in this paper confirms the experimental results for metallic waveguides obtained previously, when the polarization is perpendicular to the plane of curvature.
