  • Abstract
    In recent years, time domain-numerical analysis for sound wave propagation has been investigated widely as a result of advances in computer technology. We introduce the non-uniform grid system for the scheme combining multi-moment-MOCs, the Hybrid MM-MOC, with perfectly matched layer (PML) technique. The present results indicate that these techniques for MOCs have advantages of small memory requirements and faster calculation.
