A new method to study optical ray propagations in media with ununiform refractivity
In this paper, the ray matrix in lenslike media is derived from the simple refraction law. By introducing the equivalent index of refraction, the self-focusing phenomenon of Gaussian beam and Super-Gaussian beam are treated more intuitively. The results obtained are consistent with those derived from using other methods.
