Application of the Harmonic Analysis Technique to Determining Eddy Currents in Conducting Plates

A novel analytical approach to predict eddy currents in a conducting plate is proposed. Based upon the knowledge of the incident flux to the rectangular plate, a curve fit to a double Fourier series is obtained. This closed formula representation is used to solve the diffusion equation using the physical boundary conditions of the plate. Limitations and applicability of the method are then discussed.
