The electromagnetic field within circular apertures.

The electromagnetic field components within a circular aperture in a plane conducting screen have been investigated experimentally. The measured fields and those predicted by some recent theories are compared for plane waves irradiating the screen at normal incidence, using apertures from one-quarte...
