Abstract

The attenuation coefficient of a rectangular dielectric line
enclosed by a rectangular shield is obtained by the use of a
rigorous mode matching method to calculate the required mode field intensity. The cross-section of the waveguide is overlaid by a grid, and numerical integration is used to determine the power flow, dielectric and conductor losses and respective attenuation coefficients. To obtain experimental verification, a length of waveguide was made into a resonator, and measured and calculated Q factors compared. The results for the Ey11 mode show how the influence of the shield decreases with distance. This is
relevant to the design of dielectric waveguide structures and in filter applications where dielectric resonators are used.
