Near-field optics operates on the principle that when light interacts with objects smaller than its wavelength, it can produce an evanescent wave that decays exponentially with distance but provides ...

Introduction to SNOM: The Scanning Near-field Optical Microscope (SNOM) stands as a pivotal analytical tool in nanotechnology, enabling the visualization of nanostructures with resolution beyond the ...

The optical field with sub-nanometer confinement can greatly enhance light-matter interactions at nanoscale (e.g., enabling forbidden atomic transitions) and push extreme optical technologies (e.g., ...

Researchers have developed a new microscope that can visualize the optical response of surfaces at an unprecedented spatial resolution of one nanometer. This paves the way for optical microscopy of ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...

PEEM emerges as a key tool for imaging ultra-confined optical fields, offering high sensitivity and minimal disturbance, ...
