Abstract

A negative refractive index, a property that does not exist in natural materials, can be produced in so-called metamaterials by combining two building blocks; here it is shown that it is possible to design and fabricate a metamaterial with a negative refractive index that consists of only one type of building block by taking advantage of its crystalline structure, and this approach is demonstrated through an acoustic superlens.
