| Abstract: |
| In this talk, we will discuss subwavelength resonant modes of two hard inclusions embedding in soft elastic materials to realize negative materials in elasticity. We will show that the resonant modes are categorized into dipolar, quadrupolar, and hybrid groups, facilitating the effective realization of negative mass density, negative shear modulus and double-negative properties in elastic metamaterials. Moreover, we will analyze the stress distribution between two hard inclusions when they are closely touching. |
