Negative effective dynamic mass-density and stiffness: Micro-architecture and phononic transport in periodic composites
We report the results of the calculation of negative effective density and negative effective compliance for a layered composite. We show that the frequency-dependent effective properties remain positive for cases which lack the possibility of localized resonances (a 2-phase composite) whereas they...
