A hybrid boundary contour mode-matching (BCMM) method is described for the rigorous analysis of circular waveguide horns which combines the flexibility of the boundary contour (BC) technique for modeling the outer horn region with the efficiency of the mode-matching (MM) method for the internal horn section. A conical horn and a potter horn with an aperture diameter of about 3 λ are analyzed as examples. Excellent agreement with measurements verify the accuracy of the method
