The movement of waves, patterns that carry sound, light or heat, through materials has been widely studied by physicists, as ...

Generation of circularly polarized nonlinear signals from chiral metasurfaces with rotational symmetry under arbitrarily polarized excitation. Left and right circularly polarized light, where the ...

Chiral gold nanostars show how molecular asymmetry transfers to high-symmetry nanoparticles, producing structures with distinctive optical behavior and enhanced molecular detection. (Nanowerk ...
