Efficient and stable model reduction scheme for the numerical simulation of broadband acoustic metamaterials
The AQSRV scheme is developed for the efficient analysis of the acoustic systems. The AQSRV scheme has always a guaranteed convergence of solution. The AQSRV scheme automatically constructs the reduced model. The heuristic algorithm automatically chooses the subintervals and basis vectors. The AQSRV scheme is applied to the broadband acoustic metamaterial systems.
