研究目的
To present a general approach for the numerical calculation of the effective dielectric tensor of metamaterials and to study metamaterials beyond the long-wavelength limit, focusing on systems composed of high-refractive-index cylindrical inclusions.
研究成果
The study demonstrates that the numerical approach based on Haydock's recursion is an efficient procedure for obtaining the optical properties of metamaterials made up of cylinders with high index of refraction, incorporating resonances which cannot be explored within the long wavelength limit. The method can be generalized to arbitrary geometries and materials, making it a useful tool for the design of artificial materials with novel properties.
研究不足
The study is limited to systems composed of high-refractive-index cylindrical inclusions and does not explore other geometries or materials. The numerical approach requires a small artificial dissipative term for convergence.
