Spherical vector wave functions solution to scattering of a plane wave by a spherical shell of uniaxial anisotropic left‐handed material

Abstract

AbstractBased on the spherical vector wave function in uniaxial anisotropic left‐handed‐material (LHM), the electromagnetic fields in unbounded uniaxial anisotropic left‐handed material are expanded in terms of spherical vector wave functions in uniaxial anisotropic LHM. Applying the continuous boundary conditions of electromagnetic fields in tangential direction in the spherical shell of uniaxial anisotropic left‐handed material, the expansion coefficients of electromagnetic fields in the spherical shell of uniaxial anisotropic LHM can be derived, and then the radar cross sections (RCSs) can be obtained. Some numerical results have been given and the method in this article can be applied in the areas of antenna design and system optimization, wave propagation in complex media, and electromagnetic compatibility. © 2008 Wiley Periodicals, Inc.
