Broadband microwave absorption by logarithmic spiral metasurface
Shubo Wang, Bo Hou, C. T. Chan
We propose to use logarithmic spiral resonators for efficient absorption of microwaves. By combining their scale invariant geometries and Fabry-Perot-type resonances stemming from…
Non-Abelian gauge field optics
Yuntian Chen, Ruo-Yang Zhang, Zhongfei Xiong +4
The concept of gauge field is a cornerstone of modern physics and the synthetic gauge field has emerged as a new way to manipulate particles in many disciplines. In optics, several…
Sizable electromagnetic forces in parallel-plate metallic cavity
S. B. Wang, Jack Ng, H. Liu +3
Using a boundary element method to calculate the electromagnetic fields and the Maxwell stress tensor method to compute the electromagnetic forces, we investigate electromagnetic w…
Illusion optics: The optical transformation of an object into another object
Yun Lai, Jack Ng, HuanYang Chen +4
We propose to use transformation optics to generate a general illusion such that an arbitrary object appears to be like some other object of our choice. This is achieved by using a…
A simple route to a tunable electromagnetic gateway
Huanyang Chen, Che Ting Chan, Shiyang Liu +1
Transformation optics is used to design a gateway that can block electromagnetic waves but allows the passage of other entities. Our conceptual device has the advantage that it can…
A metamaterial frequency-selective super-absorber that has absorbing cross section significantly bigger than the geometric cross section
Jack Ng, Huanyang Chen, C. T. Chan
Using the idea of transformation optics, we propose a metamaterial device that serves as a frequency-selective super-absorber, which consists of an absorbing core material coated w…
