Comparative study of scattered electromagnetic waves from metamaterial coated cylinders

The behavior of electromagnetic wave scattering from coated cylinders of different materials is analyzed. Lengths of cylinders are infinite and coating is taken as uniform. Topological insulator cylinder coated with chiral, nihility cylinder coated with topological insulator, dielectric cylinder coated with topological insulator is considered for the analysis. Boundary value problem approach is used. Validation of formulation is confirmed by comparing numerical results with the available literature.
