ECE Seminar: Chengzhi Shi - Push Acoustic Parameters to the Extremes

Chengzhi ShiDepartment of Mechanical EngineeringUniversity of California, BerkeleyAcoustic metamaterials are artificial materials designed to realize unprecedented properties such as super-resolution imaging, asymmetric wave transport, cloaking, etc. The critical material parameters considered for the design of acoustic metamaterials are mass density and bulk modulus. Previous studies have demonstrated the existence of acoustic metamaterials with negative effective mass density and/or bulk modulus. In this talk, Chengzhi Shi will discuss the realization of acoustic metamaterials with extreme materials parameters including simultaneous zero effective mass density and infinite bulk modulus as well as complex-valued parameters.
