Electromagnetic scattering from a 2-D chiral strip simulated by circular cylinders for uniform and nonuniform chirality distribution

A semi-analytical solution is presented to the problem of electromagnetic scattering from an incident plane wave on a rectangular strip. The strip is simulated by parallel circular cylinders, illuminated by either a TE_z or a TM_z incident plane wave. The solution is based on the application of the boundary conditions on the surface of each cylinder in terms of the local coordinate system of each individual cylinder. This technique is used to predict the radar cross-section of strips composed of dielectric, conducting, and chiral material with uniform or nonuniform chiral admittance distribution.
