Abstract : Using a boundary-value treatment, a solution is obtained for the plane wave reflection from a grid of thin insulated wires buried in a homogeneous conducting half-space. A key step in the analysis is the use of an approximate impedance condition to relate the total current in the insulated grid wires and the axial component of the total electric field. Full account of the interaction of the fields with the air-ground interface is also achieved. The final result, for the specular component of the scattered field, is shown to be consistent with an equivalent transmission line circuit. The latter may also be used to predict the effect of a layer of snow or ice on the ground. (Author)
