The Kerker effect is one of the fundamental concepts in nanophotonics for controlling scattered radiation from single nanoparticles. It is based on the interaction of electric and magnetic dipoles, which, as a result of interference, determine the directional pattern of scattered radiation. The implementation of this principle allows the creation of nanoantennas that effectively redirect radiation from other nanoscale sources. This work demonstrates the possibility of dynamically controlling the directional pattern of scattered radiation by using nanoparticles made of the phase-change material Sb2Se3. The “ON” and “OFF” modes of directional scattering are shown when the phase of the material changes. These results may open up a new path in the implementation of dynamically changing nanoantennas for applications in quantum cryptography and optical telecommunications.
