Radiative heat transfer exceeding the blackbody limit between macroscale planar surfaces separated by a nanosize vacuum gap

Nature Communications, 2016
Evanescent coupling between surfaces separated by a distance smaller than the thermal wavelength can lead to radiative heat transfer greater than the blackbody limit.

The impact of coupled 3D shortwave radiative transfer on surface radiation and cumulus clouds over land [PDF]

Atmospheric Chemistry and Physics
Radiative transfer is a 3D process, but most atmospheric models consider radiation only in the vertical direction for computational efficiency. This results in inaccurate surface radiation fields, as the horizontal transport of radiation is neglected ...

On the accuracy of RTTOV-SCATT for radiative transfer at all-sky microwave and submillimeter frequencies [PDF]

, 2022
With the new generation of microwave instruments and, especially, the Ice Cloud Imager covering submillimeter frequencies, it is necessary to evaluate the performance of the operational Radiative Transfer model for TOVS (RTTOV).

Spectral Modeling of the Supersoft X-Ray Source CAL87 Based on Radiative Transfer Codes

The Astrophysical Journal, 2023
Supersoft X-ray sources (SSSs) are white dwarf (WD) binaries that radiate almost entirely below ∼1 keV. Their X-ray spectra are often complex when viewed with the X-ray grating spectrometers, where numerous emission and absorption features are ...

Retrieval of sea surface temperature from space based on modeling of infrared radiative transfer: capabilities and limitations [PDF]

, 2004
The retrieval (estimation) of sea surface temperatures (SSTs) from space-based infrared observations is increasingly performed using retrieval coefficients derived from radiative transfer simulations of top-of-atmosphere brightness temperatures (BTs ...

Linking the Monte Carlo radiative transfer algorithm to the radiative transfer equation

Monte Carlo Methods and Applications, 2023
Abstract This manuscript presents a short route to justify the widely used Monte Carlo Radiative Transfer (MCRT) algorithm straight from the Radiative Transfer Equation (RTE). In this regard, this paper starts deriving a probability measure obtained from the integral formulation of the RTE under a unidirectional point source in an ...

FDTD Simulation of Near-Field Radiative Heat Transfer between Thin Films Supporting Surface Phonon Polaritons: Lessons Learned

Journal of Thermal Science and Technology, 2013
We present the numerical simulation, using the finite difference time domain (FDTD) method, of the radiative heat transfer between two thin SiC slabs. We aim to explore the ability of the FDTD method to reproduce the analytical results for the Surface ...
