Abstract

This communication is aimed at investigating the electromagnetic (EM) characteristics of silver metal cylinder coated with homogeneous dielectric material, which is loaded with tightly wound perfectly electrical conducting sheath helix (outside of the dielectric layer) structure of different angles of orientation. Considering the L-nihility kind of behavior of silver metal at a particular frequency, the current density distributions are discussed corresponding to the parallel polarization (transverse magnetic) of the incident EM wave. The investigations are made taking into account the different values of oblique incidence, and also, the orientation angle of sheath helix structure. It is found that the current density, and hence the scattering of radiation, greatly depends on these parameters, and its magnitude increases with the increase in helix pitch as well as the angle of incidence.
