Bi, L., P. Yang, G.W. Kattawar, and M.I. Mishchenko, 2015: Optical tunneling by arbitrary macroscopic three-dimensional objects. Phys. Rev. A, 92, no. 1, 013814, doi:10.1103/PhysRevA.92.013814.

Electromagnetic wavefront portions grazing or nearly grazing the surface of a macroscopic particle contribute to the extinction of the incident radiation through a tunneling process similar to the scenario of barrier penetration in quantum mechanics. The aforesaid tunneling contribution, referred to as the edge effect, is critical to a correct depiction of the physical mechanism of electromagnetic extinction. Although an analytical solution for the edge effect in the case of a sphere has been reported in the literature, the counterparts for non-spherical particles remain unknown. The conventional curvature-based formalism of the edge effect breaks down in the case of faceted particles. As the first success, this paper reports a novel method, based on the invariant imbedding principle and the Debye expansion technique, to accurately quantify the edge effect associated with an arbitrarily shaped three-dimensional object. The present method also provides a rigorous capability to facilitate the validation of various empirical approximations for electromagnetic extinction. Canonical results are presented to illustrate optical tunneling for two non-spherical geometries.
