摘要：

A new method for solving the inner and outer radii of the 2-concentric-layer dielectric sphere is presented on the basis of the exact electromagnetic theory of scattering. Characteristic functions are introduced, of which the extremum property gives the required radius uniquely. Numerical investigations also reveal some special properties of these functions which facilitate the determination of a0 and a1 when both of them are unknown.
