The paper is devoted to the study of the connection between the numerical dispersion arising in FDTD modeling of electromagnetic signal propagation in nondispersive homogeneous media optically different from vacuum and the Courant number in the 2D case. The main results are formulated in the form of four statements, as well as a number of corollari...

In this paper we investigate the features of the numerical FDTD solution of Maxwell’s equations formulated as Cauchy problems for the corresponding homogeneous and inhomogeneous systems of equations. It is shown that for the case of time-limited field sources the Cauchy problem for an inhomogeneous system is equivalent to the corresponding Cauchy p...

This paper discusses the FDTD-algorithm for modeling electromagnetic wave propagation in randomly inhomogeneous magnetic media. We present the modeling results of square wave signals propagation in time-independent nanocomposite films with magnetic inhomogeneities of two types: with a random distribution of inhomogeneities throughout the film thick...

Currently, X-ray photoelectron spectroscopy (XPS) is widely used to characterize the nanostructured material surface. The ability to determine the atom distribution and chemical state with depth without the sample destruction is important for studying the internal structure of the coating layer several nanometers thick, and makes XPS the preferable...

In the geometry of a plane-parallel in-plane magnetized ferrite plate with dissipation, the dispersion of forward and backward magnetostatic surface waves propagating in an arbitrary direction relative to the field has been investigated. Dispersion curves as functions of the imaginary and real parts of the complex wave number has been constructed....

By means of consistent solution of the motion equation for magnetization the consideration of energy dissipation for magnetostatic surface waves propagating on in-plane magnetized ferrite plate is regarded. The complex character of the wave number caused by the dissipation is revealed. In this case the dispersion relations for the real and imaginar...

In magnetostatic approximation of electrodynamics the dispersion relation for magnetostatic back-ward volume waves (MSBVW) in a ferrite film, placed in a constant longitudinal and transverse alternating magnetic field is obtained.

Fe and (Fe) X (BaF2) Y films 10- to 160-nm-thick are grown on a polymer substrate by vacuum evaporation. The surface relief and nanostructure of the films are examined. The dependence of the conductivity on the film thickness is obtained, and a correlation between the conductivity and surface relief is found. The influence of the BaF2 dielectric ph...
