Comments on “Fundamentals of Thin-Wire Integral Equations With the Finite-Gap Generator”

In papers [1], [2], the authors extend the so-called effective current method to the Hallen´s and Pocklington´s equations with the finite-gap generator (FGG). The indicated method considered earlier in [3] with a reference to [4] is associated with application of the method of auxiliary sources to the analysis of cylindrical dipole antennas [5]-[7]. The purpose of these comments is to draw the authors´ and readers´ attention to the existence ofpaper [8] where the Pocklington´s equation with the FGG is solved for the axial current considered there to be auxiliary. The equation is solved by the Galerkin method using the piecewise sinusoidal basis and testing functions. The auxiliary axial current is used further for calculation of the surface current (which is referred to as the effective current in [1]-[4]), and the surface current itself is used for calculation of the input impedance. So, in some respects papers [1]-[7] just repeat the main idea and technique of paper [8], although of course papers [1]-[7] also contain a lot of their own new, interesting, and useful analytical and numerical results.
