ABSTRACT:
The high order mode electromagnetic wave coupler and coupling method uses one or more Y-shaped bifurcated waveguides to divide the wave to one or more order, so as to divide the target electromagnetic wave proportionally into equal shares. The waveguide is used to inject the electromagnetic wave to a main waveguide, so that the electromagnetic wave is converted into high order mode in the main waveguide. For example, a rectangular waveguide TE10mode can be converted to a circular TE01mode, wherein this conversion can also be applied to higher order modes and microwave guide-shaped modes. The coupling method includes a electromagnetic wave power dividing section and mode converting section, of which the power divider and dividing method can divide the electromagnetic wave proportionally. The coupler and coupling method feature high converting efficiency, high mode purity, high bandwidth, and convenient operation.
