Abstract:

Evanescent-wave heat transfer is the process by which near-field radiation effects are used to transfer heat from one body to another. These evanescent waves allow a thermal transmission across vacuum gaps on the scale of microns. With decreasing gap size, the heat transfer rises exceeding the far-field blackbody radiation limit. We experimentally demonstrate macroscopic evanescent-wave heat transfer between two parallel plates of sapphire. Our experimental results are in good agreement with theoretical predictions. We discuss methods for the use of evanescent-wave heat transfer to solve the cryogenic version of LIGO's cooling difficulties.
