Penetration of Electromagnetic Fields through Small Apertures in Planar Screens: Selected Data.
Abstract
Selected numerical data are presented for penetration of electromagnetic waves through apertures in planar screens. Major attention is focused upon electrically small, rectangular apertures, and for a specified length-to-width ratio, five numbers are given which enable one to compute equivalent electric and magnetic dipole moments due to an incident plane wave of any polarization, angle of incidence, and magnitude. Convergence of solutions is discussed as is the accuracy of equivalent dipole representations of fields which penetrate an aperture.
