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 with 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. The infrared imaging method has been demonstrated to be very useful for mapping the fields in a region that is sensitive to the introduction of metallic probes
