Abstract
An analysis of interfaces between isotropic and general anisotropic media, in a geometric algebra framework, is herein presented. A simple geometric approach, for certain cases of aligned anisotropy, is undertaken and compared to a more powerful, and cumbersome, approach for general anisotropy. The components of the transmitted wavenumbers for an isotropic – uniaxial and an isotropic – indefinite interface are obtained, using respectively the first and the later approach.
