Revisit the carpet cloak from optical conformal mapping
Hui Li, Yadong Xu, Qiannan Wu +1
The original carpet cloak [Phys. Rev. Lett. 101, 203901 (2008)] was designed by a numerical method, the quasi-conformal mapping. Therefore its refractive index profile was obtained…
Total reflection and transmission by epsilon-near-zero metamaterials with defects
Yadong Xu, Huanyang Chen
In this work, we investigate wave transmission through an epsilon-near-zero metamaterial waveguide embedded with defects. We show that by adjusting the geometric sizes and material…
Anti-mirror effect: A perfect lens brings a brighter feature
Yadong Xu, Shengwang Du, Lei Gao +1
In this letter, we show that a perfect lens can be employed to make multiple objects appear like only one in the far field, leading to a new concept of illusion optics. Numerical s…
An invisibility cloak using silver nanowires
Yangbo Xie, Huanyang Chen, Yadong Xu +3
In this paper, we use the parameter retrieval method together with an analytical effective medium approach to design a well-performed invisible cloak, which is based on an empirica…
