Method of separately determining electrophysical properties of bulky conductor
Abstract
A method of determining the electrical conductivity and the magnetic permeability of bulky conductors such as plates or cylinders from field intensity measurements is described, the gist being to explicate each of these two parameters from the readings of electric field intensity and magnetic field intensity at the conductor surface or in a plane of symmetry. The method is based theoretically on FourierBessel integral transformation of the differential field equations for the corresponding conductor medium. The integral relations are then mapped so as to yield the necessary relations between two field functionals and the space distributions of the electromagnetic field components. Further explication and numerical integration yield the ratio of calculated to measured conductivity and permeability. The procedure is demonstrated on a numerical example of a planeparellel field above a heavy plate.
