  • Abstract
    This paper presents a simple implicit FDTD method that is unconditionally stable. This method only requires the change of one time instant in the Yee´s algorithm to achieve the unconditional stability which is both theoretically proved and numerically verified. The resultant time step can be orders of magnitude larger than the time step allowed by the CFL condition without sacrificing the accuracy.
