ABSTRACT:
Transmission line apparatus for transmitting TE dominant electromagnetic waves is provided in accordance with the teachings of the present invention. The transmission line apparatus according to the present invention relies upon a transmission waveguide having a uniform cross-section which is substantially larger in dimension than that required for propagation of only the TE dominant electromagnetic wave desired to be transmitted. The transmission waveguide is in fact so large with respect to the transmission frequency for the TE dominant electromagnetic wave selected that a plurality of waves can form and be propagated, however, losses along the waveguide are markedly reduced. The transmission waveguide is provided with guides in the form of structure present in the waveguide which prevents a rotation of the plane of polarization of the TE dominant electromagnetic waves being transmitted. Additionally, according to further aspects of the present invention, coupling structure, which insures that only TE dominant electromagnetic waves are coupled or decoupled from the transmission waveguide are provided. This structure may comprise structure for introducing and receiving signals to be conveyed, structure for matching the boundaries of the transmission waveguide to the introducing or receiving structure and filtering structure to insure that only TE dominant electromagnetic waves are applied to and received from the transmission waveguide.
