Active control of near-field radiative heat transfer between nanoparticles and slab via the multilayered surface modes.

• We derive the formula for radiative heat flux between dipole particles and a multilayer composed of the uniaxial medium. • The multilayered surface modes can be coupled to the particle resonance, enhancing heat flux between the particle and slab. • The phase change feature of VO2 allows the active control of the heat flux by changing the slab's temperature. • We address the role of multilayer parameters on the modulation effect. • We demonstrate that the multilayered structure can also actively tune the heat flux between the nanoparticles array and slab. We derive the formula for the near-field radiative heat flux between dipole particles and a multilayered slab composed of the uniaxial medium. Based on that, the multilayered structure consisting of SiC and VO 2 materials is applied to actively modulate the radiative heat transfer between nanoparticles and slab. Utilizing the modulation feature of the multilayer, surface modes from the multilayer can be strongly coupled to the particle resonance, greatly enhancing the heat flux between the particle and slab. The phase change feature of VO 2 allows the active control of multilayered surface modes by changing the slab's temperature, greatly tuning the heat flux. We address the role of multilayer parameters on the modulation effect. We also demonstrate that the multilayered structure can also actively tune the heat flux between the nanoparticle array and slab. [ABSTRACT FROM AUTHOR]
