     This study paves the way for investigating complex contact-based dynamics of microgranular media, demonstrates a novel acoustic metamaterial, and yields a new approach to studying micro- to nanoscale contact mechanics in multiparticle networks..

   • 2016, Hou-Tong Chen, Antoinette J Taylor, Nanfang Yu, “A review of metasurfaces: physics and applications”, in arXiv‎:

     Planar metamaterials with subwavelength thickness, or metasurfaces, consisting of single-layer or few-layer stacks of planar structures, can be readily fabricated using lithography and nanoprinting methods, and the ultrathin thickness in the wave propagation direction can greatly suppress the undesirable losses.

   1. Any material that obtains its electromagnetic properties from its structure rather than from its chemical composition; especially a material engineered to have features of a size less than that of the wavelength of a class of electromagnetic radiation.
