... vector on the part of the surface where the admittance is finite and the surface electric current on the part where it is infinite, can be found by solving the inner and exterior boundary value problem. Each of the terms of the series satisfies the Meixner condition and the determined values of the tangent field on the given surface allow determining of the scattered field in the whole space. The method is illustrated with a sample of diffraction of a plane wave on a circular cylinder with the admittance ...

The problem of finding: distribution of current density on an open surface, satisfying the Meixner condition in its contour, using the given directional diagram is solved. The current is found as a series that converges to L2(s) surface norm. The conditions of realizability of the diagram are examined, and methods of determining current using ...
