A long-range, high-precision, and compact transverse displacement metrology is of crucial importance in both industries scientific researches. However, it a great challenge to measure arbitrary two-dimensional (2D) with angstrom-level precision hundred-micrometer range. Here, we demonstrated prototype high-precision 2D-displacement matrix metasurface. Light passing through the metasurface diffracted into three beams horizontal (H), vertical (V), diagonal (D) linear polarization. 2D relative...

Optical antennas enable efficient coupling between propagating light and bonding electromagnetic waves like surface plasmon polaritons (SPPs). Under the illumination of inhomogeneous optical fields, SPPs mediated by multimode could be spatially asymmetric asymmetry strongly depends on position relative to field.

Abstract Enhanced chiral optical responses of metamaterials have widespread applications in biosensor and polarization optics. Metamaterials with intrinsic chirality are commonly composed complicated 3D structures, which leads to significant fabrication challenges.
