  abstract = {<p><span>Thermal radiation through a nanohole or a nanoaperture is calculated in this paper. Results show that for aperture size ≪ dominant wavelength of thermally excited photons, heat flux deviates significantly from the well-known Planck blackbody expression of σ</span><em>T</em><span>4</span><span>, where σ is the Stefan−Boltzmann constant and&nbsp;</span><em>T</em><span>&nbsp;is the temperature. The heat flux through a nanohole is proportional to&nbsp;</span><em>T</em><span>8</span><span>&nbsp;and&nbsp;</span><em>a</em><span>4</span><span>, where&nbsp;</span><em>a</em><span>&nbsp;is the radius of the hole. Finally it is shown that for&nbsp;</span><em>aT</em><span>&nbsp;&lt; 10</span><span>6</span><span>, where&nbsp;</span><em>a</em><span>&nbsp;is expressed in nm and&nbsp;</span><em>T</em><span>&nbsp;is expressed in K, radiative heat flux through the hole is proportional to&nbsp;</span><em>T</em><span>8</span><span>&nbsp;and for&nbsp;</span><em>aT</em><span>&nbsp;&gt; 10</span><span>6</span><span>&nbsp;radiative heat flux is equal to the Planck blackbody heat flux; i.e., it is proportional to&nbsp;</span><em>T</em><span>4</span><span>.</span></p>},
