Line source excitation of multilayered metamaterial cylinders: source and scattering results

The problem of a line source radiating in the presence of a multilayered metamaterial cylinder is solved analytically and implemented numerically. Results for both the source and scattering problems demonstrate that electrically small cylindrical structures can be designed to be resonant leading to enhancements of the radiated and scattered powers. The effects of the dispersion present in the metamaterials are taken into account to study the bandwidth properties of the configurations at hand
