Field configurations and propagation constants of modes in hollow rectangular dielectric waveguides
Abstract
Field configurations and propagation constants of linearly polarized lowloss modes in hollow dielectric rectangular waveguide are computed analytically. The guide comprises an infinitely long prism of rectangular cross section embedded in a medium of complex permittivity. The magnetic permeability of free space is assigned for both media. Separate boundary equations in two dimensions and a perturbation technique applied to the two resulting boundary equations are resorted to. The dimensions of the rectangular guide cross section are assumed large compared to the freespace wavelength, so that the attenuation constant equals the sum of the TEmode and TMmode attenuation constants in parallelplate waveguide.
