Abstract: High Refractive Index (HRI) dielectric nanoparticles (NPs) can be considered as nanoantennas whose radiation directionality can be controlled depending on the incident wavelength, the surrounding medium, and the NP geometry. Here, a NP with a core-shell configuration is analysed. The core is made of an HRI material and the shell of different phase change materials (PCMs), such GaS and Sb2S3. We show how the scattered light direction can be controlled depending on the PCM phase (amorphous/crystalline).
