Torus-Projected Electromagnetic Wormholes Enabled by Anisotropic Singularity Reconstruction of Metamaterials
Junke Liao, Wen Xiao, Yixiao Ge +1
Transformation optics uses coordinate mappings to emulate curved geometries and control electromagnetic fields. However, existing approaches primarily focus on geometric deformatio…
Hyperbolic Continuous Topological Transition in Real Space
Junke Liao, Tao Hou, Huanyang Chen
Hyperbolic topological transitions refer to the transformation of is isofrequency contours in hyperbolic materials from one topology (e.g., hyperbolic) to another (e.g., elliptical…
Manifold Optics
Hongming Shen, Wen Xiao, Fei Fang Chuang +1
Transformation optics establishes an equivalence relationship between gradient media and curved space, unveiling intrinsic geometric properties of gradient media. However, this app…
Hyperbolic absolute instruments
Tao Hou, Huanyang Chen
As a lens capable of sending images of deep sub-wavelength objects to the far field, the hyperlens has garnered significant attention for its super-resolution and magnification cap…
Cosmology analogy for perfect hyperlens
Tao Hou, Wen Xiao, Huanyang Chen
With the emergence of super-resolution lenses such as superlens and hyperlens, coupled with advancements in metamaterials, the diffraction limit of approximately half wavelength is…
