The Drude model is conventionally used to explain the average motion of electrons in typical material. In this paper, we analyze the individual terms of the Drude model in order to uncover their influence on the scattering properties of small particl

The orbital evolution of interplanetary dust particles in the Solar System is governed by gravitational and non-gravitational forces. Non-gravitational effects become more significant with decreasing size of dust grains and the effects are relevant o

The explicit solution to Maxwell׳s equations that satisfies the continuity equation is obtained for electrically charged spherical particles. The traditional separation-of-variables method (SVM) cannot be used to solve the vector wave equation for a

Electromagnetic theories have reproduced the scattering properties of differently shaped particles and successfully been used to characterize numerous systems. However, certain anomalous features remain unexplained that include enhanced extinction wh

We present a remote-sensing method for identifying electrically charged droplets in clouds. Our methodology utilizes the electromagnetic (EM) radiation backscattered by the cloud at multiple wavelengths. In general, the backscatter from collections o

Physics of the Poynting–Robertson (P–R) effect is discussed and compared with the statements published in the past 30 years. Relativistically covariant formulation reveals the essence of the P–R effect and points out to nonphysical explanations

Recent studies of extended red emissions suggest the presence of very small dust particles in the Universe. The sizes of these particles can be some nanometers, thus placing the theoretical problem of their light scattering within the Rayleigh regime

In this paper, we present the physics of the gravitational effect of the Galactic bar. Our equations differ from those recently used in the literature. We apply the simultaneous action of the Galactic bar and spiral structure, together with the actio
