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

A method is proposed to improve the numerical dispersion characteristics for simulations of the scalar wave equation in 3D using the FDTD method. The improvements are realized by choosing a face-centered-cubic (FCC) grid instead of the typical Cartes

The Lebedev grid is proposed for the finite difference time domain method and compared to existing Yee grid methods. Techniques for deriving the update equations at perfect electric conductors and the intersection of two materials are presented. Resu

Gilbert's equation of motion is solved alongside Maxwell's equations with dielectric and conductive anisotropy. The algorithm is derived using only central differences and averages just like Yee's scheme for isotropic materials. This is done by using
