Abstract :
A novel stretched-coordinate form of the CFS-PML has been introduced based on the introduction of auxiliary terms that satisfy distinct auxiliary differential equations (ADE). The formulation provides a more general form for representing the CFS-PML for time-dependent solutions of Maxwell´s equations. It is found that the method is equal in effectiveness and efficiency as the CPML for FDTD simulations, and provides an efficient foundation for high-order time-dependent solutions of Maxwell´s equations.
