Until present, experimental techniques to measure the radiative heat flow relied on steady-state systems. Here, we present a dynamic measurement approach based on the transient plane source technique, which extracts thermal properties from a temperature transient caused by a step input power function. Using this versatile method, that requires only single sided contact, we measure enhanced radiative conduction up to 16 times higher than the blackbody limit on centimeter sized glass samples without any specialized sample preparation or nanofabrication.en2045-23222017113916Nature Publishing Grouphttp://rightsstatements.org/vocab/InC/1.0/applied physicsmechanical engineeringnanophotonics and plasmonicstechniques and instrumentationIngenieurwissenschaftenJournal Articleurn:nbn:de:gbv:830-8821717710.15480/882.143911420/144210.1038/s41598-017-14242-x10.15480/882.1439Journal Article
