Abstract :
The present analysis in this paper makes use of mode matching to characterize each discontinuity of the horn by means of a generalized scattering matrix. The generalized scattering matrices are then combined together to completely describe the behaviour of the horn. This development takes into account the coupling between the guides at the input and the aperture furcated junctions. Consequently, both the amplitude and phase patterns as well as the input match are accurately predicted. They have been verified by extensive comparisons with measured results of a C-band horn at Lockheed Martin
