摘要：
The "optimal" speedup of an explicit and unconditionally stable time-domain method, without sacrificing accuracy, is the ratio of the time step required by accuracy to the time step determined by stability. In this work, by significantly accelerating the explicit time-marching-based revealing of the stable modes for any given time step, it is demonstrated that it is feasible to achieve a more than optimal speedup.
