| Popis: |
This chapter describes the operation of the E ‐plane waveguide tee junction. An understanding of the operation of this class of circuit requires an appreciation of the eigenvalue problem. The E ‐plane tee junction dealt in the chapter is also known as a shunt circuit. The off/on E ‐plane switch is a large gap or non‐evanescent geometry. It is off state is obtained by optimizing the details of a quarter‐wave long demagnetized Faraday section on one narrow wall of the waveguide together with the details of a two‐layer quasi‐planar resonator. The chapter reviews the nature of the even and odd field patterns of the junction. The operation of E ‐plane ferrite switches using quarter‐wave long resonators mounted in the H ‐plane of a rectangular waveguide may be obtained by having recourse to its eigenvalue problem. A typical stop or pass band filter may be converted to a pass or stop band by either retuning its even or odd eigen‐networks. |
