Romanov A.V. and Yurkin M.A. Rigorous analysis of the spectral sizing of single particles based on light scattering patterns, Opt. Laser Technol. 151, 108047 (2022). (PDF)

The sizing of particles based on the Fourier transform of its light-scattering patterns has been known for a long time. But it has always been an empirical technique, mostly ( Read more... )

This paper started with a simple idea to improve the Wentzel-Kramers-Brillouin (WKB) approximation for the internal fields inside large optically ( Read more... )

Unusual way to spend my birthday - I have visited Sochi for the congress of young scientists, organized by Russian government. It was rather meaningless from a scientific point of view (too broad topics), but interesting from organizational one (I have never attended such a huge conference organized on a high level) and good for networking. I have ( Read more... )

Moskalensky A.E. and Yurkin M.A. A point electric dipole: From basic optical properties to the fluctuation-dissipation theorem, Rev. Phys. 6, 100047 (2021). (PDF)

This was a very long journey... The paper started in the fall of 2019 with a small (and focused) question of how to properly define the fluctuation dissipation theorem for a point dipole ( Read more... )

Haven't been flying since March 2020, but last week I managed to visit the offline conference. This is even more valueable, since the perspectives of further offline conferences are very unclear. Here are the photos of small resort village Divnomorskoe in the Gelendzhik region on the shore of Black Sea, which can probably be considered a typical ( Read more... )

Feng X., Wang J., Teng S., Xu X., Zhu B., Wang J., Zhu X., Yurkin M.A.,  and Liu C. Can light absorption of black carbon still be enhanced by  mixing with absorbing materials? Atmos. Environ. 253, 118358 (2021). (PDF)

This paper is dedicated to mixing of black-carbon fractal aerosols with brown-carbon coating. In contrast to non-absorbing coatings ( Read more... )
