Performance of surface impedance integral equations for quasi-stationary field analysis in axisymmetric systems

Surface integral equations satisfied by the induced current density are formulated for axisymmetric solid conductors by applying the surface impedance model and the perfect conductor model. Their performance for an elementary implementation is investigated employing spheres and also prolate and oblate conducting spheroids with various range of geometric parameters. The accuracy of the technique employed is determined for different basis functions and different weighting functions. Numerical results generated are compared with available analytical results and with experimental data.
