Radiative heat exchange between closely spaced objects can be greatly augmented at nanoscale separation due to photon tunneling and enhanced density of states. Furthermore, the interaction of electromagnetic waves with micro/nanostructured materials can modify and control their far-field radiative properties. Micro/nanoscale thermal radiation deals with both near-field radiative heat transfer between closely spaced objects and interactions of electromagnetic waves with micro/nanostructured materials that could manipulate their far-field radiative properties.
Graphene and other van der Waals two-dimensional materials offer possibility of further enhancing near-field radiative heat transfer as well as tailoring far-field radiative properties. Nanoscale thermal radiation has promising applications in advanced energy harvesting, nanomanufacturing, thermal control and management, and high-resolution thermal mapping.
This presentation will give an overview of the past and present developments of near-field thermal radiation research and the related short-term and long-term application prospects.
