We observe impedance matched coupling between molecular vibrations and infrared optical antennas. Broadband synchrotron near-field spectroscopy reveals antenna-vibration hybridization, mode splitting, and tip excitation of coupled dark plasmon modes.
Scattering scanning near field microscopy is capable of measuring the response of a material to incident infrared light with a resolution determined by the tip radius of the antenna. We present new methods and results here, in which broad band and ultrafast sources are used to extend this technique into the time and frequency domains.
We demonstrate multispectral infrared vibrational scattering-scanning near-field optical microscopy. Spatio-spectral images with 10 nm spatial and 1 cm−1 spectral resolution reveal nano-phase behavior in molecular nanostructured model systems with unprecedented sensitivity and structural detail.
We have undertaken an analysis of the Voyager photopolarimeter (PPS) stellar occultation data of Saturn's A ring. The Voyager PPS observed the bright star δ Scorpii as it was occulted by Saturn's main rings during the spacecraft flyby of the Saturn system in 1981. The occultation measurement produced a ring profile with radial resolution of approximately 100 m, and radial structure is evident in the...
