Summary The diffraction of the principal mode at the open end of a semi-infinite parallel-plate waveguide terminated by an infinite plane flange (double-wedge) is studied in the interval 0.1≤ka≤1.7, where k is the wave number and 2a is the guide width. The evanescent-mode correction to the reflection amplitude and the amplitudes of the evanescent modes are computed by three different approximation methods. The agreement among these methods in the considered interval is good. The evanescent-mode correction to the reflection coefficient is small, but the correction to the phase is quite large, attaining values of the order of 10% for ka ∼1.7. The domain of applicability of the various methods is discussed.
