Initial value problems of cylindrical electromagnetic waves propagation in a nonlinear nondispersive medium

Physical Review E, 2013
We introduce a simple method to estimate the accuracy of exact solutions under initial value conditions proposed by Petrov and Kudrin [Phys. Rev. Lett. 104, 190404 (2010)]. We demonstrate that even for a sufficiently weak nonlinearity, the initial value condition difference between linear and nonlinear case may be evident.

On a Nonlinear Eigenvalue Problem Related to the Theory of Propagation of Electromagnetic Waves

Differential Equations, 2018
The eigenvalue problem is studied for a quasilinear second-order ordinary differential equation on a closed interval with Dirichlets boundary conditions (the corresponding linear problem has an infinite number of negative and no positive eigenvalues).

Solution of the direct problem of electromagnetic waves propagation in foams

2016 XXIst International Seminar/Workshop on Direct and Inverse Problems of Electromagnetic and Acoustic Wave Theory (DIPED), 2016
Model of water foam presented from 7 layers with different dielectric characteristics for thickness 5, 10 and 15 mm. Calculations were made in microwave band of 8–12 GHz. Layers have value of foaming ratio from 6 till 350. The results of reflection and transmission characteristics show dependence from thickness of layers in range of 5–15 mm.

On the problem of nonlinear coupled electromagnetic transverse-electric–transverse magnetic wave propagation

Journal of Mathematical Physics, 2013
Coupled electromagnetic TE and TM wave propagation in a nonlinear plane layer is considered. Nonlinearity inside the layer is described by Kerr law. Physical problem is reduced to a nonlinear two-parameter eigenvalue problem for a system of (nonlinear) ordinary differential equations.

Effective Field Method in the Problem of Electromagnetic Wave Propagation Through a Medium With Isolated Inclusions

Journal of Electromagnetic Waves and Applications, 1997
Summary: Effective field method is applied for the calculation of the phase velocities and attenuation factors of plane monochromatic electromagnetic waves in a dielectric medium with an array of spherical inclusions. The results of calculation are investigated in a wide region of the volume concentrations of inclusions and frequencies of the exciting ...

Electromagnetic Symmetric Hybrid Wave Propagation Problem in a Medium with Arbitrary Nonlinear Saturation

2019 Photonics & Electromagnetics Research Symposium - Fall (PIERS - Fall), 2019
The paper treats a problem of propagation of electromagnetic symmetric hybrid wave in a plane non-homogeneous nonlinear dielectric waveguide. The physical problem is reduced to a nonlinear transmission eigenvalue problem for Maxwell’s equations with appropriate boundary and transmission conditions.
