Elastic Waves Scattering without Conversion in Metamaterials with Simultaneous Zero Indices for Longitudinal and Transverse waves
Fengming Liu, Zhengyou Liu
We theoretically investigate elastic waves propagating in metamaterials with simultaneous zero indices for both the longitudinal and transverse waves. With scattering objects (here…

Three dimensional Dirac point at k=0 in photonic and phononic systems
Xueqin Huang, Fengming Liu, C. T. Chan
While "Dirac cone" dispersions can only be meaningfully defined in two dimensional (2D) systems, the notion of a Dirac point can be extended to three dimensional (3D) classical wav…

Dirac Cones at k=0 in Phononic Crystals
Fengming Liu, Yun Lai, Xueqin Huang +1
We show that two-dimensional phononic crystals exhibit Dirac cone dispersion at k=0 by exploiting dipole and quadrupole accidental degeneracy. While the equi-frequency surface of D…
