Models that place design constraints on devices which are used to measure the leakage currents in high-resistivity semiconductor materials are presented. If these design constraints are met, these models can then be used to quantitatively predict the

This paper describes an experimental study of the shielding of 60 Hz magnetic fields with nested long cylinders with open ends and short cylinders with capped ends, constructed from multiple layers of steel and aluminum. Measurements of shielding fac

A method is described for calculating the induced current distribution within a thin, nonferrous conducting plate with finite dimensions in the presence of an imposed magnetic field due to specified source conductors. The induced current solution is

The basic principles that underlie materials-based quasistatic magnetic shielding are described. Shielding mechanisms are identified and shown in specific examples that involve long cylindrical and spherical shield geometries. Analytic results are gi

Power-frequency (50/60-Hz) magnetic fields produced by electric blankets are estimated using a three-dimensional computer model. Maximum, minimum, and volume-averaged fields within human forms are presented as a function of blanket type and a number

An integral equation method is presented for solving the inverse shaping problem where a desired free boundary is specified in addition to the location of a number of source currents. The method results in a matrix equation which is solved for the so
