摘要:

The amplitude distribution in the scalar far-field approximation is derived as a simple expression, involving only sinc functions, in terms of two non-orthogonal coordinates related to the lengths and directions of two sides of the triangle. Photographs are juxtaposed with computed contours to show the real and the imaginary parts of this expression.
