Quasiclassical Dynamics of Nonlinear Wave Systems
Radiophysics and Quantum Electronics - - 2024
E. A. Kuznetsov
The paper presents a brief review of the quasiclassical wave dynamics for the nonlinear Schrödinger equation (NLSE) as applied to focusing and defocusing media. The NLSE depends significantly on the space dimension d. The two-dimensional NLSE has an additional symmetry of the conformal type with respect to the Talanov transformations (Talanov in JETP Lett. 11:199–201, 1970), which were initially f...... hiện toàn bộ
Two-Frequency Coherence Function for the Field of a Wave Propagating Through a Multiscale Randomly Inhomogeneous Medium
Radiophysics and Quantum Electronics - Tập 61 - Trang 259-271 - 2018
M.V. Tinin
We study the possibilities of integral representation for the two-frequency mutual coherence function of the wave field in a randomly inhomogeneous ionosphere. The integral representation was obtained using the Double Weighted Fourier Transform (DWFT) method. We point out that the conditions of validity of the geometrical-optics approximation for frequency coherence are weaker than the same condit...... hiện toàn bộ
The Influence of the Motion of a Strongly Magnetized Plasma on Radiation from a Traveling-Wave Antenna
Radiophysics and Quantum Electronics - - 2018
D. D. Bareev, V. G. Gavrilenko, V. D. Pikulin
We consider the problem of radiation from a traveling-wave antenna in a warm electron plasma which moves along a strong magnetic field at a constant velocity. To describe the electromagnetic properties of the plasma, we use the diagonal tensor of dielectric permittivity, which is calculated for a magnetized plasma with the Maxwellian electron velocity distribution allowing for collisions of electr...... hiện toàn bộ
The absorption of a plane electromagnetic wave in a circular plasma cylinder
Radiophysics and Quantum Electronics - Tập 14 - Trang 915-920 - 1971
Yu. V. Bogomolov
Experimental Study of the Nonstationarity of an Oblique Ionospheric Sounding Signal on a Mid-Latitude HF Radiopath
Radiophysics and Quantum Electronics - Tập 47 - Trang 552-559 - 2004
V. V. Bochkarev, I. R. Petrova, V. Yu. Teplov
We consider issues relating to the nonstationarity of an oblique ionospheric sounding signal. Experimental data obtained with the Doppler goniometric facility of the Kazan State University are used. The equipment, methods of measurement, and the algorithms used for analysis of the experimental data are described. Typical coherence ranges of an ionospheric signal measured in the daytime at differen...... hiện toàn bộ
Accuracy of body-rotation-parameter measurement with monochromatic illumination and two-element reception
Radiophysics and Quantum Electronics - Tập 35 - Trang 284-287 - 1992
I. V. Kholin
Analysis of the components of optimum processing of a backscattered field is used to derive analytic formulas for the accuracy of estimation of the proper-rotation velocity-vector components of an illuminated body in the general case of progressive—rotational motion. It is shown that two-element measurement is considerably more accurate than single-element.
Possible statistical “acceleration” of photons in a turbulent plasma
