Analytical Method for Metasurface-Based Cloaking Under Arbitrary Oblique Illumination
Yi Zhang, Haiyan Fan, Yujie Zhang +3
The performance of antennas can severely deteriorate in the presence of adjacent electrically-large scatterers. In this work, we use a conducting hollow cylinder to shield the scat…

Ultra-wideband Antireflection Assisted by Continuously Varying Temporal Medium
Yi Zhang, Liang Peng, Zhengjie Huang +2
We demonstrate that reflectionless propagation of electromagnetic waves between two different materials can be achieved by designing an intermediate temporal medium, which can work…

An Invisible Metallic Mesh
Dexin Ye, Ling Lu, John D. Joannopoulos +2
We introduce a solid material that is itself invisible, possessing identical electromagnetic properties as air (i.e. not a cloak) at a desired frequency. Such a material could prov…
