Solution of the inverse problem of eddy-current location as applied to a plate

The direct problem of eddy-current location was solved in [1-3] by calculating the field of an eddy-current transducer that was situated above a half-space, a plate, and a two-layer product and was powered by pulses with a high duty cycle. Using [2], we solve the inverse problem: it is assumed that the field of the system is known and is measured a specified time after the pulse ends, and the plate parameters - thickness and electrical conductivity - are calculated.
