Abstract

High frequency fields refracted by a geometry, which contains a plano-convex lens placed at a certain distance from a plane uniaxial interface, are derived by using Maslov's method. Maslov's method predicts the field in the caustic region by combining the simplicity of ray and generality of the transform method. Numerical computations are made for the field pattern around the caustic. The results are found in good agreement with results obtained using Kirchhoff's approximation.
