Second harmonic generation (SHG) in plasmonic nanostructures is often enhanced by matching their localized surface plasmon resonance (LSPR) either with the excitation 10,11 or, more rarely, the ...
A team of physicists from ITMO University, MIPT, and The University of Texas at Austin have developed an unconventional nanoantenna that scatters light in a particular direction depending on the ...
