Abstract
The inset dielectric guide (IDG) is just a rectangular groove filled with dielectric, which retains many of the advantages of dielectric guides, without fabrication and loss problems. Quasi-planar IDGs are attractive for applications in microwave and millimeter-wave frequency ranges, as they can be used as low loss and low cost transmission lines, directional couplers, nonreciprocal phase shifters, antennas and other devices. In this paper we address circular IDG-type structures, investigating hybrid wave propagation in single microslot lines loaded with semi-circular dielectric cylinders. The analysis is based on systems of singular integral-integrodifferential equations of the first kind. The proposed algorithms are rapidly convergent, yielding very accurate results for the propagation constants and for the modal equivalent magnetic currents of the principal as well as the higher-order modes.
