High frequency field expressions are derived around feed point of a two dimensional cassegrain system using the Maslov's method. Maslov's method is a systematic procedure for predicting the field in the caustic region combining the simplicity of ray theory and generality of the transform method. Numerical computations are made for the analysis of field pattern around the caustic of a cassegrain system.
