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

At the University of Calgary, we piloted an integrated curriculum approach in second-year electrical engineering. The intention was to provide authentic learning experiences, with the ultimate goal of fostering deep learning in the students. To impro

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 collocated Lebedev grid has previously been proposed as an alternative to the Yee grid for electromagnetic finite-difference time-domain (FDTD) simulations. While it performs better in anisotropic media, it performs poorly in isotropic media beca

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

The finite-difference time-domain method is derived on a Lebedev grid for lossy anisotropic media. The Lebedev grid uses collocated field components and supports spurious solutions but an intuitive method for removing the extra solutions is presented

The standard FDTD method for Maxwell's equations is reformulated on face-centered cubic (FCC) grids as an alternative to the standard Cartesian (Yee) grid. Dispersion and stability for the formulation are also presented, and a comparison is made with

Maxwell's equations are discretized on a Face-Centered-Cubic (FCC) lattice instead of simple cubic to improve grid isotropy of the numerical simulation. Explicit update equations and numerical dispersion expressions are derived. The method is tested

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
