1. A method of determining electric field properties of an inhomogeneous target, comprising the steps of:

  • (A) measuring the electric field external to a boundary that defines the target;

    (B) estimating electric property distributions on a coarse mesh discretization of the target; and

    (C) computing an electric field on a fine mesh discretization of the target, and at points external to the fine mesh discretization, the fine mesh having finer discretization than the coarse mesh and being overlapping with the coarse mesh.
