The problem of scattering from an infinitely long conducting cylinder partially buried in a perfectly conducting ground plane due to an obliquely incident plane wave (a three-dimensional problem) is solved by an exact procedure based on the method of images. The incident field, the reflected field from the ground plane, and the scattered field from the cylinder and its image are expressed in terms of cylindrical vector wave functions. By satisfying the boundary conditions on the surface of the cylinder, a set of two coupled infinite systems of equations for the even-and odd-mode expansion coefficients of the scattered field is obtained. These equations are solved numerically. Related quantities, i.e., the induced current in the cylinder and the scattered power patterns in the far field, are obtained, and their variations with respect to the angle of incidence, the height (depth) above (below) the ground plane, and the electrical radius are studied for the TM case.
