Systematic realization of double-zero-index phononic crystals with hard inclusions

Abstract A systematic process is described to realize double-zero-index phononic crystals with Dirac-like points experimentally. This type of crystal normally has softer inclusion material than its surroundings medium, allowing mapping into a zero-index medium under certain conditions but also makin...
