"Breakthrough: Measuring Near-Field Subwavelength Thermal Radiation"

Researchers have successfully conducted the first near-field thermal radiation measurement between subwavelength nanodevices, breaking Planck's Law at the nanoscale. By fabricating an advanced instrument, they observed a 20-fold enhancement in heat transfer between two subwavelength surfaces with a separation gap of 150 nm, providing new insights into energy transport physics within nanodevices. This foundational physics has the potential to impact thermal engineering and photonics in the future.
