Abstract

A low-frequency stimulated scattering (LFSS) signal caused by pulsations of nanospheres under an electromagnetic field is detected in an aqueous suspension of dielectric nanospheres of three diameters (∼74 nm, ∼292 nm, and ∼540 nm) at various particle concentrations. The frequency shifts of the scattering line, calculated based on the developed model, are in good agreement with the measurement results.
