A number of canonical problems that describe the coupling of electromagnetic fields through apertures into enclosed regions have been solved. The scattering data generated by these cavity‐backed aperture solutions share a common property: they are dominated by resonance features closely connected to the presence of the cavity. The behavior of these cavity‐backed aperture resonance features has been characterized for variations in frequencies, angles of incidence, look angles, aperture sizes, and interior object properties. It has been found that the scattering cross sections contain information about the interior of the cavity.
