Solutions to the problem of radiation of Hertzian dipoles in stratified uniaxially anisotropic media are obtained by decomposing a general wave field into transverse electric and transverse magnetic modes. With the use of primary excitation fields due to a Hertzian dipole embedded in an anisotropic medium, the electromagnetic fields in stratified anisotropic media are derived by applying the appropriate boundary conditions. General expressions for fields due to vertical electric, vertical magnetic, horizontal electric, and horizontal magnetic dipoles are presented. Numerical computations were carried out for the case of a vertical electric Hertzian dipole in a uniaxially anisotropic substrate backed by a ground plane.
