Three-Dimensional Anisotropic Metamaterials as Triaxial Optical Inclinometers

Abstract Split-ring resonators (SRRs) present an attractive avenue for the development of micro/nano scale inclinometers for applications like medical microbots, military hardware, and nanosatellite systems. However, the 180° isotropy of their two-dimensional structure presents a major hurdle. In th...
