A mathematical model and a computational method for studying the influence of the particle diffusion on equilibrium shapes of a magnetic liquid is developed. It is then applied on the ferrohydrostatic problem of doubly connected equilibrium shapes of a magnetic fluid located on a horizontal plate around a vertical cylindrical conductor with a direct current. Numerical simulations show the limit...

We unveil the relationship between two anomalous scattering processes known as Kerker conditions and the duality symmetry of Maxwell equations. We generalize these conditions and show that they can be applied to any particle with cylindrical symmetry, not only to spherical particles as the original Kerker conditions were derived for. We also explain the role of the optical helicity in these sca...

An Object Oriented Particle-in-Cell model of a plasma glow discharge in a cylindrical magnetron cleaning device has been developed to provide guidance in developing a novel in situ surface conditioning technique. The model tracks the trajectories of particles by solving the equations of motion and the electrostatic field equations. Simulation results are compared to experimental measurements ob...

Metal nanoparticles are efficient resonant plasmonic scatterers for light, and, if placed on top of a high-index substrate, can efficiently couple light into the substrate. This coupling, however, strongly depends on particle shape and surrounding environment. We study the effect of particle shape and substrate refractive index on the plasmonic resonances of silver nanoparticles and we systemat...

Relativistic magnetized jets, such as those from AGN, GRBs and XRBs, are susceptible to current- pressure-driven MHD instabilities that can lead particle acceleration non-thermal radiation. Here we investigate the development of these through 3D kinetic simulations cylindrically symmetric equilibria involving toroidal magnetic fields with electron-positron pair plasma. Generalizing recent treat...

We present a microfluidic particle-trap array that utilizes negative dielectrophoresis (nDEP) force and hydrodynamic force. The traps are located at the stagnation points of cylindrical pillars arranged in a regular array, and they can function as both single-particle traps (capable of discriminating particles based on size) and multiparticle traps (capable of controlling the number of particle...
