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…
Theory of optical imaging beyond the diffraction limit with a far-field superlens
Stephane Durant, Zhaowei Liu, Nicholas Fang +1
Recent theoretical and experimental studies have shown that imaging with resolution well beyond the diffraction limit can be obtained with so-called superlenses. Images formed by s…
