Abstract

A novel implementation of the perfectly matched layer (PML) absorbing boundary condition (ABC) to terminate the finite‐difference time‐domain (FDTD) algorithm for general dispersive and negative index materials is presented. The proposed formulation also adopts the complex frequency‐shifted (CFS) approach, involves simple FDTD expressions and avoids complex arithmetic. Several FDTD‐PML simulations with different parameters are conducted for the termination of various dispersive media validating the stability, accuracy and effectiveness of the schemes and indicating the advantage of the CFS‐PML.

## Abstract The focus of this comment is to discuss an important point regarding the derivation of the wave equation in the perfectly matched layer (PML). It is demonstrated that the distance dependency of the PML conductivity profile should be taken into consideration when deriving the wave equati

## Abstract A time‐domain nonlinear model representing the propagation of ultra‐short optical pulses in dispersive materials containing second order nonlinearity is presented. The model accounts for material dispersion through Lorentz model in addition to the spatiotemporal coupling between the pul
