Anisotropic virtual gain and large tuning of particles’ scattering by complex-frequency excitations

Year: 2024

Type: article

Abstract: The authors show how the use of suitable time-domain pulses, characterized by a complex frequency, can turn anisotropic losses to anisotropic virtual gain in small particles. These excitations can largely tune the scattering off particles without requiring any other tuning mechanism.
