Maxim A. Yurkin
Maxim A. Yurkin received his BS and MS degrees in physics from the Novosibirsk State University (NSU) with honors (2002, 2004), and dual PhD in computational science and biophysics from the University of Amsterdam and Voevodsky Institute of Chemical Kinetics and Combustion (ICKC, Novosibirsk), respectively (2007). His research interests include the theory and simulations of electromagnetic scattering, the discrete dipole approximation (DDA), and inverse light-scattering problems. Specifically, he has made multiple important contributions to the theory and numerical efficiency of the DDA, and is the main developer of the open-source ADDA code. He received inaugural Young Scientist’s Award in electromagnetic and light scattering from Elsevier (2007) and two Prizes of the Academia Europaea for Russian young scientists (2010, 2016).
The discrete dipole approximation for light-scattering simulations
Light scattering is widely used in remote sensing of various objects ranging from metal nanoparticles and macromolecules to atmospheric aerosols and interstellar dust, being in some cases the only available approach to characterize their geometric or optical properties. All these applications require accurate simulations, which are not trivial for particles of arbitrary shape and internal structure. The discrete dipole approximation (DDA) is one of the general methods to handle such problems. In this talk I will start with an introduction to the DDA, including both the basic underlying physical picture and rigorous derivation starting from the integral form of Maxwell’s equation for the electric field. The latter shows that the DDA is a numerically exact method and a special case of volume-discretization method of moments. Importantly, the DDA applies to almost any electromagnetic problem involving non-magnetic particles. It can handle arbitrary shaped beams, particles in complicated environments (e.g., on a multi-layered substrate), and simulate a broad range of quasi-classical electromagnetic phenomena (such as emission enhancement, near-field radiative heat transfer, and electron energy-loss spectroscopy). I will also discuss computational aspects, including the latest efficiency improvements, and the existing open-source DDA codes that largely explain the method’s popularity. Finally, I will highlight current capabilities and limitations (open questions) of the DDA.

Digital holography for particle characterization: optical compression and contribution of the direct problem modeling
Fabrice R.A. Onofri, Lilian Chabrol

Digital holography is a volumetric optical technique with unique features for real-time 3D characterization of particulate media. However, it remains limited by two critical factors: the lack of precision of the propagation and diffusion model used for inversions or direct calculations, and its inability to analyze media other than highly diluted ones. In this work, we attempt to overcome these limitations by introducing a model combining geometrical optics and physical optics, whose accuracy is assessed using Lorenz-Mie and Debye theories coupled with the localization principle, and a new method of optical compression of holograms.

Super-resolution Fluorescence and Quantitative Phase Microscopy Visualize Live Cells in 3D
Optical three-dimensional (3D) microscopy is of great importance in many fields, especially in biology. Due to the transparency of biological samples (such as biological cells) under visible light, optical 3D microscopy is often implemented with fluorescence imaging, phase contrast imaging, or other nonlinear processes to enhance the contrast of intracellular structures. In this talk, two 3D optical microscopic technique, namely, sparse scanning structured illumination microscopy (SS-SIM) and quantitative phase contrast tomography (QPCT), will be presented.
In SS-SIM, structured patterns of different orientations and different phase shifts are generated by resonantly scanning a focused light and modulating its intensity sinusoidally. As a consequence, super-resolution and optical-sectioned fluorescence imaging with a penetration depth of ~300 micrometers can be performed, implying a great potential for deep tissue imaging. In QPCT, 24 LEDs distributed on a ring are lighted up one by one sequentially to generate oblique illuminations at different angles, and quantitative phase contrast imaging for each illumination is carried out by retardering the dc term for four different phase shifts with an ultra-fast SLM. A 3D tomographic phase map is reconstructed from the complex amplitudes obtained at different illumination angles. Both the SS-SIM and QPCT were utilized to obtain 3D subcellular organelles inside live COS7 cells. The comparison of the two imaging modalities tells that SS-SIM enables visualization of specific subcellular organelles in virtue of fluorescence tagging. While, QPCT can visualize up to ten types of subcellular organelles once for all, for that nearly all the subcellular organelles have different refractive index above the cytosol. The combination of the 3D fluorescence and phase images provide complementary information for the same sample, contributing to revealing the mechanisms of many life events.
