侥幸心理摘要:A waveguide connection comprising the combination of a rectangular waveguide, an elliptical waveguide having a cutoff frequency and impedance different from tho of said rectangular waveguide, an inhomogeneous stepped transformer joining said rectangular waveguide to said elliptical waveguide, said transformer having multiple ctions all of which have inside dimensions small enough to cutoff the first excitable higher order mode in a prelected frequency band, each ction of said transformer having a transver cross-ction defined by the equation: (2x/a).sup.p +
(2y/b).sup.p =1, where a is the dimension of the inside surface of said cross-ction along the major transver axis, b is the dimension of the inside surface of said cross-ction along the minor transver axis, and x and y define the location of each point on the inner surface of the cross-ction with reference to the coordinate system established by the major and minor transver axes of the cross- ction, respectively, the value of said exponent p increasing progressively from the ction adjacent to said elliptical waveguide to the ction adjacent to said rectangular waveguide, and the magnitudes of a and b changing progressively from step to step along the length of said transformer so that both the cutoff frequency and the impedence of said transformer change monotonically along the length of said transformer.
