Abstract The fields in transition and caustic region of dielectric coated objects are obtained by geometric theory of diffraction. In transition region, direct computation is accomplished by modifying the residue series solution. The equivalent currents are extended to deal with the creeping wave in caustic region. The comparison of computation resuts with the eigenfunction solution shows that the presented methods are efficient.
