A variant of the finite-difference time-domain (FDTD) algorithm—the Lebedev FDTD method—is augmented to allow for the simulation of electromagnetic waves in general dispersive anisotropic materials. Distinct dispersions may be applied to each of

Maxwell's equations are discretized on a Face-Centered Cubic (FCC) lattice instead of a simple cubic as an alternative to the standard Yee method for improvements in numerical dispersion characteristics and grid isotropy of the method. Explicit updat

The Lebedev grid is an alternative to Yee grid where, because the discretized fields lie at the same location in space, there is no need for further field interpolations when modeling anisotropic materials. In this letter, we focus on accurately impl

The Lebedev method is a collocated scheme which makes it more suitable for modelling anisotropic materials compared to Yee method as it removes the need for interpolation since all the field components exist at one location. In this work, we accurate

A broadband beam-shifter is designed based on the well-known transformation optics technique. The beam-shifter can be also used as a polarization splitter if it is designed to only affect one polarization. The required material parameters are then re

The standard Yee grid, though simple and robust, is not well suited to modeling anisotropic media. In contrast, the Lebedev grid is well suited, but is computationally more expensive. A methodology is presented to use the classical Yee grid in isotro
