Dirac Spectra and Edge States in Honeycomb Plasmonic Lattices
Dezhuan Han, Yun Lai, Jian Zi +2
We study theoretically the dispersion of plasmonic honeycomb lattices and find Dirac spectra for both dipole and quadrupole modes. Zigzag edge states derived from Dirac points are…

A Dynamical Effective Medium Theory for Elastic Metamaterials
Ying Wu, Yun Lai, Zhao-Qing Zhang
We develop a dynamical effective medium theory to accurately predict the unusual properties of elastic metamaterials in two dimensions near the resonant frequencies. The theory sho…
