A THEORETICAL AND EXPERIMENTAL ANALYSIS OF QUASISTATIC MAGNETIC FIELD TRANSMISSION THROUGH CIRCULAR APERTURES,

Abstract

In studies related to protection against the Electromagnetic Pulse (EMP) resulting from nuclear explosions, electromagnetic shielding theory is applied to military electrical systems. Many complex boundary value problems must be solved in order to estimate the EMP effects on such a system. The complexity of these 'real world' problems is such that rigor must be sacrificed for engineering judgment if any estimates of EMP effects are to be obtained in a reasonable time frame. For instance, apertures that appear in equipment enclosures, cabinets, missiles, etc., are examples of such 'real world' problems. Transmission through circular apertures in long hollow cylindrical enclosures is frequently of interest in dealing with such systems. We consider the determination of interior fields for a hollow cylinder of infinite length with a circular aperture, which is uniformly immersed in a time varying axial magnetic field. (Author)
