The Toronto Maple Leafs are reportedly attempting a last-minute effort to re-sign pending unrestricted free agent Steven ...

The idea of a particle that races faster than light has long fascinated physicists. Known as the tachyon, it was originally ...

Relaxation model is absent in metamaterial research. view more Credit: Xinmin Fu, Yajuan Han et al. Polarization is one of the most important electromagnetic (EM) properties of dielectric materials.

Electromagnetic acoustic transducer (EMAT) is a kind of non-contact ultrasonic transducer, and during its operation, no liquid coupling is required. Despite this advantage, EMAT has low transduction ...

A concise formulation of the frequency-dependent finite-difference time-domain (FDTD) method is presented using the trapezoidal recursive convolution (TRC) technique for the analysis of a ...

A temporal and spatial simulation and design of nanoplasmonic laser based on a semiconductor nanodisk is presented in this paper. A body-of-revolution finite-difference-time-domain (BOR-FDTD) ...

A highly accurate and numerically stable model of Lorentz dielectric dispersion for the finite-difference time-domain (FDTD) method is presented. The coefficients of the proposed model are optimally ...

In contrast, for metamaterials, there are only two models: Drude model for infinitely long wires, and Lorentz model for resonant structures (e.g., short metallic wires and split-ring resonators ...

The electromagnetic responses of metamaterial microstructural units are typically described using classical polarization theory models from dielectric physics, such as the Lorentz and Drude models ...

We present what we believe to be the first algorithms that use a simple scalar-potential formulation to model linear Debye and Lorentz dielectric dispersions at low frequencies in the context of ...

The implicit finite-difference time-domain (FDTD) method based on the locally one-dimensional scheme is extended to the frequency-dependent version for the analysis of the Drude-Lorentz model. The ...
