摘要：
The electromagnetic field close to a pyramidal horn antenna has been predicted using a numerical technique assuming a spherical phase front in the aperture of the horn. Comparison to experimental results using an infrared imaging technique has shown that the best fit is for a phase front that is 1.25 times more curved than a sphere.
