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…
Whispering gallery mode enhanced optical force with resonant tunneling excitation in the Kretschmann geometry
J. J. Xiao, J. Ng, Z. F. Lin +1
The boundary element method is applied to investigate the optical forces when whispering gallery modes (WGMs) are excited by a total internally reflected wave. Such evanescent wave…
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…
Strong optical force induced by morphology dependent resonances
Jack Ng, Zhifang Lin, C. T. Chan +1
We consider the resonant optical force acting on a pair of transparent microspheres by the excitation of the Morphology Dependent Resonance (MDR). The bonding and anti-bonding mode…
