Electromagnetic stress tensor for amorphous metamaterial medium
Neng Wang, Shubo Wang, Jack Ng
We analytically and numerically investigated the internal optical forces exerted by an electromagnetic wave inside an amorphous metamaterial medium. We derived, by using the princi…
Optical trapping of anti-reflection coating-coated spheres
Neng Wang, Xiao Li, Jun Chen +2
It was theoretically proposed and experimentally demonstrated that anti-reflection coating allows one to trap a high dielectric sphere, at the same time enhancing the transverse op…
Decomposition of optical force into conservative and nonconservative components
Yikun Jiang, Jun Chen, Jack Ng +1
We present a multipole expansion theory for optical force exerting on a particle immersed in generic monochromatic free-space optical field. Based on the theory, we have, for the f…
Ab initio derivation of multipolar expansion of optical force
Yikun Jiang, Jack Ng, Zhifang Lin
Like many other physical quantities, the optical force can be expanded using multipole expansion, which has been done in [Nat. Photon. 5, 531], up to electric octupole order. Howev…
Universal relationships between optical force/torque and orbital versus spin momentum/angular momentum of light
Yikun Jiang, Huajin Chen, Jun Chen +2
We establish universal relationships between optical force/torque on a general particle and different parts of linear and angular momentum (AM) of generic monochromatic optical fie…
Electromagnetic stress at the boundary: photon pressure or tension?
Shubo Wang, Jack Ng, Meng Xiao +1
It is well known that incident photons carrying momentum hk exert a positive photon pressure. But if light is impinging from a negative refractive medium in which hk is directed to…
