Optical antennas transform light from freely propagating waves into highly localized excitations that interact strongly with matter. Unlike their radio frequency counterparts, optical antennas are ...
Plasmon-enhanced molecular spectroscopies have attracted tremendous attention as powerful detection tools with ultrahigh sensitivity down to the single-molecule level. The optical response of ...
The copper target was operated at voltages of 11 kV, 12 kV, 13 kV, and 14 kV for the electron source, and a 50 kV configuration using a molybdenum target was used as a representative example for the ...
Atoms emit unique light wavelengths when electrons change energy levels. A star's temperature and composition are revealed by its light spectrum. Strongest hydrogen lines appear in stars around 10,000 ...
On August 19, 2022, solar astronomers using the Daniel K. Inouye Solar Telescope (DKIST) on the Hawaiian island of Maui ...
