Abstract

For pt.I see ibid., vol.36, no.5, p.651 (1988). The coherent and incoherent responses of conducting axially corrugated surfaces (which are on the average circular cylinders) are calculated. The calculation encompasses second-order perturbation. The general approach used is to apply the extinction theorem to write an integral equation for the surface current density, and then to use the perturbation theory to solve it. The results are recast by using Pade approximants to achieve a significant extension of the domain of validity of the original formulation
