TLDR
In this article, the amplitude curves of the interior and aperture fields as functions of position for a variety of cavity and aperture sizes were obtained and the results exhibited in the form of amplitude curves.Abstract:
A plane wave is symmetrically incident on a spherical shell with a circular aperture. The fields inside and outside the cavity are expanded in terms of spherical vector wave functions and the modal coefficients are found by application of the least squares method to the boundary conditions. Computed data are obtained and the results exhibited in the form of amplitude curves of the interior and aperture fields as functions of position for a variety of cavity and aperture sizes. Within the cavity it appears that the field variations are primarily determined by the cavity size and that the aperture size serves only to scale them.read more

Electromagnetic penetration through apertures in conducting surfaces
TL;DR: In this paper, a tutorial review of a number of methods for analyzing such aperture problems is presented with an emphasis on techniques, and an extensive set of representative numerical results is included. But the discussion presented herein is reasonably self-contained and is supplemented by references to classical as well as current approaches to the aperture problem.

Electromagnetic scattering from and transmission through arbitrary apertures in conducting bodies
TL;DR: In this paper, the general 3D aperture coupling problem is formulated in terms of an integral equation for the equivalent magnetic current in the aperture, which is numerically solved by the method of moments.

Electromagnetic Field Penetration into a Cylindrical Cavity
TL;DR: For an E-polarized plane wave incident on a perfectly conducting cylindrical shell having a longitudinal slit aperture, the fields inside the cavity were determined by a numerical solution of the E-field integral equation as discussed by the authors.

Electromagnetic scattering of an arbitrary plane wave from a spherical shell with a circular aperture

Scattering by a spherical shell with a circular aperture
TL;DR: In this paper, the authors studied the electromagnetic scattering behavior of a spherical shell with a circular aperture, where the shell was assumed to be perfectly conducting and infinitesimally thin, and was illuminated by a plane wave symmetrically incident upon the aperture.
