Photonic thermal switch via metamaterials made of vanadium dioxide-coated nanoparticles.In this work, a photonic thermal switch is proposed based on the phase-change material vanadium dioxide (VO2) within the framework of near-field radiative heat transfer (NFRHT).  The proposed switch opens pathways for active control of NFRHT and holds practical significance for developing thermal photon-based logic circuits.
