Abstract

We investigated magnetostatic field penetration into multiple annular apertures in a thick conducting plane. We rigorously solved a magnetostatic boundary-value problem of multiple annular apertures using the Hankel transform, eigenfunction expansion, and superposition. We represented magnetic polarizability in a rapidly convergent series and computed it in terms of aperture geometry and incident angles to understand the magnetostatic field penetration.
