Theory of Systems with Thin Impedance Dipoles and Narrow Slots

Abstract

Scattering, excitation, and radiation of electromagnetic waves by a system with finite dimensional material bodies and coupling holes cut between two electrodynamic volumes is considered. Integral equations system defining densities of electric currents on linear dipoles and equivalent magnetic currents in coupling holes were formulated based on boundary conditions on dipoles and continuity conditions for tangential components of magnetic fields in the coupling holes. Quasi-one-dimensional equations uniquely determining currents in the system elements were obtained by using physically based transition from obtained two-dimensional integral equations. The thin linear impedance dipoles may have irregular geometric and electrophysical characteristics along their length and the narrow slots may be arbitrary cut in surfaces of two electrodynamic volumes. Combined multielement dipole-slot structures may have the same properties.
