SUMMARY:From effective medium to double-zero-index materials - Ying Wu (Ki
 ng Abdullah University of Science and Technology (KAUST))

DESCRIPTION:Keqiang Lyu (KAUST)\, Changqing Xu(Nanjing Normal University)\
 , Yun Lai(Nanjing University) and Guancong Ma(Hong Kong Baptist University
 )\nIn this presentation\, I will provide a brief overview of various homog
 enization schemes developed for periodic structures. Specifically\, I will
  focus on the multiple-scatterin based effective medium\, and elucidate th
 e link between effective properties and local resonances.Next\, I will del
 ve into the latest developments in double-zero-index materials\, where per
 mittivity and permeability\, or mass density and compressibility\, can sim
 ultaneously become zero. I will highlight the role played by effective med
 ium theory in designing these materials. To demonstrate how to achieve the
  desired resonances leading to double-zero index\, I will showcase several
  examples\, including three-dimensional electromagnetic and acoustic metam
 aterials\, as well as a two-dimensional acoustic metamaterial.
