Strong plasmon coupling between two gold nanospheres on a gold slab
H. Liu, J. Ng, S. B. Wang +3
In this work, the plasmon coupling effect between two gold nanospheres on a gold slab is investigated. At plasmon resonance frequencies, electrons on the surface of the slab are ab…
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…
Backward Pulling Force from a Forward Propagating Beam
Jun Chen, Jack Ng, Zhifang Lin +1
A photon carries a momentum of, so one may anticipate light to "push" on any object standing in its path via the scattering force. In the absence of intensity gradient, using a lig…
Strong light-induced negative optical pressure arising from the kinetic energy of conduction electrons in plasmonic cavities
H. Liu, Jack Ng, S. B. Wang +4
We found that very strong negative optical pressure can be induced in plasmonic cavities by LC resonance. This interesting effect could be described qualitatively by a Lagrangian m…
