基于COMSOL Multiphysics有限元法的声人工结构负切模量分析
Investigation of negative shear modulus of artificial acoustic structures by finite element simulation based on COMSOLMultiphysics
摘要
Abstract
Designed an artificial acoustic structure made of coated cells. Dispersion relation ofthis structureis investigated byfinite element simulations of COMSOL Multiphysics software.This structure is found to exhibit negative shear modulus whichis caused by the resonant rotational mode.关键词
