Spoof Plasmon Hybridization
Jingjing Zhang, Zhen Liao, Yu Luo +3
Plasmon hybridization between closely spaced nanoparticles yields new hybrid modes not found in individual constituents, allowing for the engineering of resonance properties and fi…
Homogeneous optical cloak constructed with uniform layered structures
Jingjing Zhang, Liu Liu, Yu Luo +2
The prospect of rendering objects invisible has intrigued researchers for centuries. Transformation optics based invisibility cloak design is now bringing this goal from science fi…
Macroscopic Invisibility Cloaking of Visible Light
Xianzhong Chen, Yu Luo, Jingjing Zhang +3
Invisibility cloaks of light, which used to be confined to the imagination, have now been turned into a scientific reality, thanks to the enabling theoretical tools of transformati…
Cloaking of levitating objects above a ground plane
Jingjing Zhang, Yu Luo, Niels Asger Mortensen
An approach to hiding objects levitating or flying above a conducting sheet is suggested in this letter. The proposed device makes use of isotropic negative-refractive-index materi…
Minimizing the scattering of a non-magnetic cloak
Jingjing Zhang, Yu Luo, Niels Asger Mortensen
Nonmagnetic cloak offers a feasible way to achieve invisibility at optical frequencies using materials with only electric responses. In this letter, we suggest an approximation of…
A Rigorous Analysis of Plane-transformed Invisibility Cloaks
Yu Luo, Jingjing Zhang, Hongsheng Chen +3
The electromagnetic characteristics of plane-transformed invisibility cloaks are quantitatively studied in this paper. We take elliptical cylindrical cloak as the example, and use…
Wave and ray analysis of a type of cloak exhibiting magnified and shifted scattering effect
Yu Luo, Jingjing Zhang, Hongsheng Chen +3
Ray-tracing exercise and full-wave analysis were performed to validate the performance of a new type of cloak composed of isotropic metamaterials. It is shown that objects inside t…
A new strategy to conceal an object from electromagnetic wave
Yu Luo, Jingjing Zhang, Hongsheng Chen +2
A new recipe for concealing objects from detection is suggested. Different with traditional cloak which deflects light around the core of the cloak to make the object inside invisi…
Cylindrical Cloak with Axial Permittivity/Permeability Spatially Invariant
Yu Luo, Jingjing Zhang, Hongsheng Chen +2
In order to reduce the difficulties in the experimental realizations of the cloak but still keep good performance of invisibility, we proposed a perfect cylindrical invisibility cl…
Controlling the Emission of Electromagnetic Sources by Coordinate transformation
Yu Luo, Jingjing Zhang, Lixin Ran +2
The coordinate transformation on the space that contains electromagnetic sources is studied. We find that, not only the permittivity and permeability tensors of the media, but also…
Design and analytically full-wave validation of the invisibility cloaks, concentrators, and field rotators created with a general class of transformations
Yu Luo, Hongsheng Chen, Jingjing Zhang +2
We investigate a general class of electromagnetic devices created with any continuous transformation functions by rigorously calculating the analytical expressions of the electroma…
