This demonstration is a step toward the development of plasmonic chips, so called because they use plasmons—collective excitations of electrons in a conductor—rather than electrons to transfer and ...

This video illustrates a 180 nm, 30 µm, 11 Hz, scan of diffraction grating taken with Bruker’s Dimension FastScan atomic force microscope (AFM). The Dimension FastScan provides high resolution and ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...
