Abstract :
A quadrature scheme is described for the calculation of the radiation field of an open-ended guiding structure directly from the longitudinal field components of the mode in the aperture. The calculated radiation pattern for a rectangular waveguide and a regular polygon dielectric rod agree well with known results. Radiation patterns for rectangular dielectric rod are also presented.
