The problem of a buried axial Hertzian dipole placed at the end of a semi-infinitely long metallic tube is associated with the investigation of electromagnetic through-the-earth propagation. Under a thin-tube approximation explicit analytic expression of the far-field is obtained by employing the Wiener-Hopf technique. Numerical results are presented in this paper for various dipole locations and ground conductivities. The improvement over the result based upon a Kirchhoff's approximation is noted.
