超材料与电磁场中三种具体的手性将被讨论:双负材料(double-negative material)的左手手性(left-handedness)特征,平面波的极化手性,以及材料中的偏光性(chirality)。由这三种手性出发,还将讨论左手手性与右手手性之间的对称性。负折射(negative refraction)与回波特性(backward-wave characteristic)将在媒质分解本征波(eigen...
Negative refraction (NR) metamaterials are featured with unique physical properties and potential to realize full control of electromagnetic waves, which have attracted much attention since the last decade. However, few researches focus on the realization of three-dimensional dielectric NR metamaterials in...
Spatial dispersion, anisotropy, and negative refraction with negative group velocity have been observed in metamaterials. Spatial dispersion occurs when permittivity epsilon(omega, kappa) and permeability mu(omega, kappa) are dependent on frequency, omega, and wave vector, kappa, related to a fixed ...

内容提示: In 2000, an artificially structured composite was shown to exhibita negative index of refraction over a band of microwavefrequencies1. This demonstration of a previously unexploitedelectromagnetic (EM) property proved the importance ofengineered materials and has resulted in an extraordinary ...
