I wonder if anyone has tried measuring the field distribution close to an antenna aperture using probes? Possibly, such near field measurements could then be used to determine the emissivity or reflectivity of materials placed in front of the antenna. In this way one could use near field measurements rather than the traditional far field measurements.
