Definite photon deflections of topological defects in metasurfaces and symmetry-breaking phase transitions with material loss
Chong Sheng, Hui Liu, Huanyang Chen +1
Combination of topology and general relativity can lead to some profound and farsighted predictions. It is well known that symmetry breaking of the Higgs vacuum field in the early…
Transformation devices with optical nihility media and reduced realizations
Lin Xu, Qiannan Wu, Yangyang Zhou +1
Starting from optical nihility media (ONM), we design several intriguing devices with transformation optics method in two dimensions, such as a wave splitter, a concave lens, a fie…
Geodesic conformal transformation optics: manipulating light with continuous refractive index profile
Lin Xu, Tomáš Tyc, Huanyang Chen
Conformal transformation optics provides a simple scheme for manipulating light rays with inhomogeneous isotropic dielectrics. However, there is usually discontinuity for refractiv…
Light rays and waves on geodesic lenses
Lin Xu, Xiangyang Wang, Tomáš Tyc +4
Starting from well-known absolute instruments for perfect imaging, we introduce a type of rotational-symmetrical compact closed manifolds, namely geodesic lenses. We demonstrate th…
Compact Acoustic Retroreflector Based on A Mirrored Luneburg Lens
Yangyang Fu, Junfei Li, Yangbo Xie +4
We propose and demonstrate a compact acoustic retroreflector that reroutes probing signals back towards the source with minimal scattering. Gradient refractive index (GRIN) acousti…
