Analytical expression for reflected field of a vertical electric dipole over an uniaxial medium half-space

An analytical expression was derived for the electromagnetic field of a vertical electric dipole over an uniaxial medium half-Space.The two Sommerfeld type integrals contained in the field components were expressed as a rapidly and absolutely convergent series of spherical standing wave functions;and these coefficients of the series were cast into the Legender polynomials with complex argument for the medium parameter by using the techniques of the hypergeometric functions.The obtained solution for the Sommerfeld half-Space problem has the advantage that it is accurate and efficient and can conveniently be employed to calculate and analyze the electromagnetic field.
