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