A method of determining material parameters associated with a conductor using four points includes injecting and extracting alternating current into the plate using current-carrying wires operatively connected to two of the four points, measuring potential drop between the remaining two of the four points, and calculating the material parameters. The conductor can be of a homogenous material, a stratified material, or other type of material. The conductor can have any number of geometries, including that of a plate, a cylinder, a tube, a stratified cylinder or other shape. |
