▼ [18p-P9-13] Analysis of Cylindrical Hyperbolic Metamaterials by using Effective Medium Approximation
キーワード：Hyperbolic Metamaterials, Nanophotonics, Plasmonics
The cylindrical hyperbolic metamaterials (CHMMs) have recently gained a significant role in the field of metamaterials and nano-photonics.They display strong anisotropy and hyperbolic (or indefinite) dispersion, which originates from one of the principal components of their electric permittivity or magnetic permeability tensors having the opposite sign to the other two principal components. These subwavelength scale metal and dielectric nanostructures have opened up exciting opportunities for manipulating the optical responses. Such anisotropic structured materials exhibit unusual optical properties, including strong enhancement of spontaneous emission, negative refraction and enhanced super-lensing effects.
We are investigating these structures by means of effective medium approximation (EMA), to establish a comprehensive model. This work can also give an insight into the physics behind the optical response and other interesting phenomena such as super scattering, invisibility and absorption associated with CHMMs. The EMA can also significantly reduce the computational efforts needed to simulate the electromagnetic response of these systems. Study of these hyperbolic structures is important as they can have different applications in nanotechnology like low scattering near field optical microscope, invisible photodetectors and metamaterials, super-scattering etc.
