Dispersive Behavior of Plasmonic and Metamaterial Coating on Achieving Transparency

Dispersive effect through the Drude and Lorentz model is studied on achieving transparency and reduction of the total scattering cross section of a spherical scatterer. Some full wave numerical results in frequency domain are presented and illustrated that dispersion as a constraint, limiting the bandwidth of transparency phenomenon. The losses are also included and shown that for low losses there is not much difference in comparison with the lossless cases.
