Description

The change in complex impedance between an ideal one-turn circular coil located above and parallel to a conducting half-space with respect to a similar isolated coil has been calculated. From this result a series expansion of the integrand allows the solution to be approximated by terms expressed as complete elliptic integrals. Results have been calculated for the change in impedance as a function of the lift-off distance and the conductivity of the half-space for a coil of representative.radius.

The Impedance of a Loop Near a Conducting Half-Space

The change in complex impedance between an ideal one-turn circular coil located above and parallel to a conducting half-space with respect to a similar isolated coil has been calculated. From this result a series expansion of the integrand allows the solution to be approximated by terms expressed as complete elliptic integrals.
