Enhanced Surface Photon Drag on Plasmonic Metamaterials: A Fizeau-Doppler Shift Study
Leilei Yin, Nicholas X. Fang
In this work, we numerically study the Fizeau-Doppler shift of surface modes in a moving plasmonic metamaterial. At proper surface plasmon resonance conditions, a slow group veloci…
Molecular Scale Imaging with a Smooth Superlens
Pratik Chaturvedi, Wei Wu, VJ Logeeswaran +5
We demonstrate a smooth and low loss silver (Ag) optical superlens capable of resolving features at 1/12th of the illumination wavelength with high fidelity. This is made possible…
Imaging of plasmonic modes of silver nanoparticles using high-resolution cathodoluminescence spectroscopy
Pratik Chaturvedi, Keng Hsu, Anil Kumar +2
Cathodoluminescence spectroscopy has been performed on silver nanoparticles in a scanning electron microscopy setup. Peaks appearing in the visible range for particles fabricated o…
Focusing Ultrasound with Acoustic Metamaterial Network
Shu Zhang, Leilei Yin, Nicholas Fang
We present the first experimental demonstration of focusing ultrasound waves through a flat acoustic metamaterial lens composed of a planar network of subwavelength Helmholtz reson…
