Interference-exact radiative transfer equation. [PDF]

open access: yesSci Rep, 2017
AbstractThe Purcell effect, i.e., the modification of the spontaneous emission rate by optical interference, profoundly affects the light-matter coupling in optical resonators. Fully describing the optical absorption, emission, and interference of light hence conventionally requires combining the full Maxwell’s equations with stochastic or quantum ...

Generation of Synthetic Non-Homogeneous Fog by Discretized Radiative Transfer Equation [PDF]

open access: yesJournal of Imaging
The synthesis of realistic fog in images is critical for applications such as autonomous navigation, augmented reality, and visual effects. Traditional methods based on Koschmieder’s law or GAN-based image translation typically assume homogeneous fog ...

A Reduced Basis Method for Radiative Transfer Equation [PDF]

open access: yesJournal of Scientific Computing, 2022
Linear kinetic transport equations play a critical role in optical tomography, radiative transfer and neutron transport. The fundamental difficulty hampering their efficient and accurate numerical resolution lies in the high dimensionality of the physical and velocity/angular variables and the fact that the problem is multiscale in nature.

A Nonlinear Moment Model for Radiative Transfer Equation [PDF]

open access: yesMultiscale Modeling & Simulation, 2021
We derive a nonlinear moment model for radiative transfer equation in 3D space, using the method to derive the nonlinear moment model for the radiative transfer equation in slab geometry. The resulted 3D HMPN model enjoys a list of mathematical advantages, including global hyperbolicity, rotational invariance, physical wave speeds, spectral accuracy ...
