Through analytical derivations and numerical simulations, negative refraction and refractive steering of elastic waves are realized with the IA mechanism. The positive (negative) inertia of the system can be tuned by the IA angle, which determines whether the passband of the lattice is positive (...

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 ...

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(...
The physics of electromagnetic wave propagation in metamaterials with negative refractive index has been studied extensively in recent years, but realistic and computationally efficient numerical models for such media are now just beginning to e merge.Su
