Analytical modeling of rotating field eddy current sensor for nondestructive testing of tubes

Rotating field eddy current sensor for nondestructive testing of tubes has been recently proposed as an alternative to the state-of-the-art eddy current array probes and mechanically rotating probes. In this paper we present an analytical approach to modeling of such a sensor based on the second-order vector potential and series eigenvalue expansion. The modeling results are compared with the results obtained using finite element method.
