Enhanced Far-Field Emission Via Dual Reststrahlen Bands in h-BN/SiO <sub>2</sub> Bilayer
nanoribbon. We identify the confined modes within the Reststrahlen bands with numerical modeling, revealing the enhancement mechanism. This effect is verified with direct thermal measurements by using a thermal bridge method, yielding a peak emissivity of 0.6. This work offers insights into engineering broad-band polaritonic thermal emitters.
