Guided modes spectrum of the elliptical dielectric waveguide has been completed and correspondence bet ween modes in circular, elliptical, rectangular and slab dielectric waveguides have been investigated with details. Based on the results, an elliptical model description technique for planar waveguides has been suggested. This technique has, by exemple, been shown to be applicable for lower order modes in microslot lines and open suspended strip-line. Elliptical dielectric waveguide is also shown as a very practical structure to approximate dielectric resonator of high permittivity with various shapes. |
