Until now, optical antennas could almost always be described classically: the electrons of the metal simply stop at the edge ...

optical antennas, surface plasmon and phonon polaritons, extreme nonlinear optics, strong light matter interaction. Scanning probe near-field optical microscopy and spectroscopy, optical forces, and ...

With thousands or even millions of tiny antennas in an array, each only 1 micrometer wide, the researchers can capture the scattered light with an optical microscope and measure electrical signals ...
