Scattering from strip-loaded composite chiral cylindrical structure

In this work, the analytic representation of two-dimensional dyadic Green´s function of a perfectly conducting cylinder coated with one-layered chiral medium is successfully derived and and explained in terms of the normalized cylindrical vector wave functions. Then, the integral equation is formulated for governing the current on the loaded strip for TM-wave normal incidence. By enforcing the Galerkin´s procedure, the strip current is expanded in the form of a series of Chebyshev polynomials of the first kind. Furthermore, numerical calculations are performed to examine the chirality effect on the scattered fields in the far-zone
