Dual-Symmetric Form of Integral Equations for Antenna Currents

A generalized formulation of integral equations for currents in electrically thin radiators of electric and magnetic type satisfying the principle of permutational duality is offered. The methodological feature of the approach is based on a concept of effective induced impedances of electric and magnetic types, which is used for solutions of boundary value problems. Such alternative representation of the integral equations makes it possible to combine solution methods known for electrically thin vibrators and slot antennas based on a single methodology.
