description In various types of EMP simulators, the existence of spurious electrons is an annoying problem. To reduce this effect, charged wire structures have been employed. The solution of a wire mesh charged to a sufficiently high negative potential to repel these unwanted electrons has previously been handled theoretically by conformal transformation for the limiting case of thin-wire structures. The generalized case of finite-radii cylindrical structures has also been dealt with previously by Fourier transformation. In the present work, separation of variables and the method of moments have been used for a two-dimensional study of the problem of a cylindrical satellite with a periodic structure of narrow sheets having a constant negative voltage. The result is applicable to repelling unwanted electrons in system-generated EMP simulators. The technique is general and hence can easily be extended to the case of a coaxial line with slots as well as other shielding enclosures and similar applications.< >
