Abstract Kerker effect is one of the unique phenomena in modern electrodynamics. Due to overlapping of electric and magnetic dipole moments, all-dielectric particles can be invisible in forward or backward directions. In our paper we propose new cond

We present new isochrone fits to the colour-magnitude diagrams of the Galactic globular clusters NGC\,6362 and NGC\,6723. We utilize 22 and 26 photometric filters for NGC\,6362 and NGC\,6723, respectively, from the ultraviolet to mid-infrared using d

We present the results of our BVR-band photometric and R-band polarimetric observations of ∼40 stars in the periphery of the dark cloud CB54. From different photometric data, we estimate E(B − V) and E(J − H). After involving data from other so

Relations between Laplace’s spheroidal harmonics associated with different spheroidal coordinates are derived. The transition matrices for the functions of the 1st kind are lower triangular and are related by inversion. The matrices for the functio

We consider new approaches to the calculation of the optical properties of small nonspherical layered particles whose layer boundaries are nonconfocal concentric coaxial ellipsoids. A simple analytical approximation is proposed and substantiated for

We have constructed a spheroidal model to solve the problem of light scattering by nonspherical particles. The semiaxes of the model spheroid are determined based on the requirement that the volumes of initial and model particles are equal, as well a

We consider the light scattering by layered spheroids that are small compared to the wavelength of the incident radiation. Simple approximate formulas are obtained for the polarizability of such particles with nonconfocal spheroidal surfaces of layer

We construct a Rayleigh approximation for multilayer particles the layer boundaries of which are nonconfocal spheroids. The geometry of the problem is taken into account to the maximum extent by representing the field potentials inside nonconfocal sh

Using the solution of the problem of light scattering by a homogeneous spheroid, derived by separation of variables in spheroidal coordinates, we find the ‘spheroidal’ T -matrix. We suggest a transformation of this matrix into the ‘spherical’
