| Abstract: | The numerical simulation and theoretical analysis for Phase velocityproperties of the remote field eddy current(RFEO) is presented in the paper bythe electromagnetic (EM) field theory and EM computation. Comparisons of thephase velocities between the EM field and the EM wave are given. It can be seenthat the research of RFEC in thin paper is of imPOrtance for Promoting theapplication of the RFEO technique to practical use. |
