Illustration of nanolight pseudo-birefringence. Two-step excitation via a light-illuminated antenna and a sharp boundary efficiently excites higher-order light-matter waves (hyperbolic phonon ...

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 ...

A new two-step excitation technique efficiently generates and separates different modes of hyperbolic polaritons - directional nanoscale light-matter modes with extreme electromagnetic field ...
