Generic Cartesian spatial cell (i,j) and surrounding cells in the 2D computational domain. Stored values for each cell are the z-component of the electric field at time n and position (i,j), the x-component of the magnetic field at time n + 1/2 and position (i,j + 1/2), and the y-component of the magnetic field at time n + 1/2 and position (i + 1/2,j).
