Optical Theorem for Measuring the Acoustic Extinction Cross Section of Helmholtz Resonators
Vladimir Igoshin, Daniil Klimov, Yuri Utkin +5
The optical theorem is a powerful tool of scattering theory that directly relates the extinction cross section of a scatterer to its forward scattering amplitude. While widely used…
Experimental Investigation of Acoustic Kerker Effect in Labyrinthine Resonators
Iuliia Timankova, Mikhail Smagin, Mikhail Kuzmin +4
Controlling the directionality of the acoustic scattering with single acoustic metaatoms has a key importance for reaching spatial routing of sound with acoustic metamaterials. In…
Optical Spintronics: Towards Optical Communication Without Energy Transfer
Ilya Deriy, Danil Kornovan, Mihail Petrov +1
Energy, momentum, and angular momentum are fundamental properties tied to the symmetries of space and time, with photons and other elementary particles acting as carriers of these…
Excitation of surface plasmon-polaritons through optically-induced ultrafast transient gratings
Olesia Pashina, Albert Seredin, Giulia Crotti +4
Ultrafast excitation of non-equilibrium carriers under intense pulses offer unique opportunities for controlling optical properties of semiconductor materials. In this work, we pro…
