Numerical Investigation Into A New Shape Of Metamaterials At Optical Frequencies

The development of metamaterials was driven by the desire to fulfill synthetic materials with optical properties beyond naturally available materials. Natural isotropic homogeneous materials are characterized by a frequency dependent permittivity ε(ω) and permeability μ(ω). Both of ε(ω) and μ(ω) describe the response of the media to an electromagnetic field, where ε(ω) describes the electric polarization induced by the electric field and μ(ω) describes the magnetic polarization induced by the magnetic field. In the optical domain, where the magnetic response is vanishing, the permeability is a constant equal to unity. In this paper, a new shape of structure made of mercury metal was modeled and simulated. It shows that this structure acts as a double negative material at a specific ranges of the optical frequencies. The study cover numerical investigation on the reflectance, transmission and absorption behavior of this new structure, the parameters of the material including permittivity, permeability and refractive index. Then the study shows the effect of the different radius of the nanowires on the structure behavior. After that, I plot the E-Field, H-Field and surface current for some frequencies.
