摘要: In this paper a new concept for multi-mode resonators is presented, which based on combined TE- and TM-mode operation in dielectric rods. By proper arrangement of rods branch configuration, fundamental eigenmode resonances could be shown to present. planar realization triple quadruple mode are obtained. With non-planar, three dimensional the sextuple possible. symmetry considerations, field patterns first 12 modes - guided along determined. Mode charts finite elements calculations threefold symmetric resonator structure.
