Duplex Mikaelian lenses and duplex Maxwell's fish eye lenses
Huiyan Peng, Senlin Liu, Yuze Wu +6
In this paper, we report two new kinds of absolute optical instruments that can make stigmatically images for geometric optics in two dimensional space. One is called the duplex Mi…
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…
Self-focusing and the Talbot effect in conformal transformation optics
Xiangyang Wang, Huanyang Chen, Hui Liu +3
Transformation optics (TO) has been used to propose various novel optical devices. With the help of metamaterials, several intriguing designs, such as invisibility cloaks, have bee…
Accidental degeneracy and topological phase transitions in two-dimensional core-shell dielectric photonic crystals
Lin Xu, HaiXiao Wang, YaDong Xu +2
A simple core-shell two-dimensional photonic crystal is studied where the triangle lattice symmetry and rotation symmetry leads to rich physics in the study of accidental…
