Integral equations for dielectric-coated thin-wire antennas

The generalization of Pocklington's integral equation for thin-wire structures of arbitrary geometry with dielectric coating is discussed. The deduction of the integral equation is given, based on the definition of the general electric field as the sum of field current on conductor surface, field of polarization current that is equivalent to dielectric coating and primary field. The primary field can be the field of a localized source (the problem of excitation) or the field of incident plane electromagnetic waves (the problem of scattering). Numerical results are found to be in a good agreement with experiments and with the data obtained by other authors.
