A 3D vector LGA model for computational electromagnetics

Lattice gas automata (LGA) are an alternative to the traditional differential equation based numerical methods now widely used in computational electromagnetics[1]. Lattice gas automata are based on studying the behaviour of an extremely large array of simple cells. The states of the cells are very simple, usually consisting of only a few bits per cell. A lattice gas is a microscopic description of physics of the problem being modelling, where the bits in the cell can be envisioned as particles which are intended to mimic the interaction of particles on the lattice. The LGA evolves in discrete time steps, where all cells in the lattice are updated in synchronism according to the sample simple rule.
