Higher-order unconditionally stable algorithms to solve the time-dependent Maxwell equations
Higher-order unconditionally stable algorithms to solve the time-dependent Maxwell equations
For the recently introduced algorithms to solve the time-dependent Maxwell equations [J. S. Kole, M. T. Figge, and H. De Raedt, Phys. Rev. E 64, 066705 (2001)], we construct a variable grid implementation and an improved spatial discretization implementation that preserve the exceptional property of the algorithms to be unconditionally …
