The characteristic biquadratic: An illustration of transmission in anisotropic media
Michael A. Slawinski
Methods describing ray bending at interfaces between anisotropic media are often very complicated. Under the assumption of weak anisotropy, and considering quasi- compressional waves, a concept of graphical illustration of analytical expressions governing the ray bending is presented. The main purpose of the presented approach is to gain an intuitive understanding of anisotropic phenomena.
