Scattering of Electromagnetic Radiation by Apertures. XIII. The Electric Field in the Slot Near the TM01 Cutoff for a Longitudinally Narrow Slotted Conducting Cylinder.
Abstract
The fields for an infinite slotted circular cylinder are derived for arbitrary incidence and polarization. For a narrow slot and E-polarized incident radiation a large field amplitude is shown to occur in the slot at non-resonant frequencies. For the lowest modes the resonance line in the slot is calculated for a very narrow aperture at normal, symmetric incidence. Measurements in the slot of a finite cylinder are shown along with the effects of varying slot angle, slot length and cylinder length. (Author)
