Direction-Selective Wave Freezing and Amplification at a Hyperbolic Time Interface
Zhao Wang, Ai Gang, Xinghong Zhu +3
Hyperbolic media are well known for converting high k-components that are evanescent in conventional dielectrics into propagating bulk waves through their open equifrequency contou…
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…
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…
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…
