Abstract
An analytical method for determining the degree of wave refraction is investigated. The ray tracing method previously used to calculate wave propagating cannot explain the degree of refraction caused by different kinds of conditions. In this study, we suggest the index of refraction degree using the principle that refraction is caused by the difference of phase velocities along the crest line.
