Electromagnetic Modeling of Scattered GNSS Signals

IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
The quasi-specular reflection collected under the illumination of signals of opportunity can exhibit temporal fluctuations related to the characteristics of the surface roughness. Even in quite flat regions, gentle undulations, i.e., those comparable with the wavelength over the vertical scale and much longer over the horizontal one, can exist and can ...

Modelling the radiative electromagnetic field

International Journal of Computing Science and Mathematics, 2008
The radiative electromagnetic field is generated during the experiments with a radiation and is of importance for spacecrafts under sun radiation and for the radio-electronic equipment of the nuclear reactor control systems. The paper presents the developed methods of modelling the multistage process of the radiative electromagnetic field excitation ...

Electromagnetic Modeling and Simulation

2014
This unique book presents simple, easy-to-use, but effective short codes as well as virtual tools that can be used by electrical, electronic, communication, and computer engineers in a broad range of electrical engineering problems. Electromagnetic modeling is essential to the design and modeling of antenna, radar, satellite, medical imaging, and other

Geometrical Model of Electromagnetic Fields

American Journal of Physics, 1963
The electrostatic field, electromagnetic waves, electromagnetic induction, and the pure magnetic field are illustrated and explained in terms of a single pictorial representation of the general electromagnetic field of a classical charged particle.

Numerical modeling of electromagnetic casting processes

Journal of Computational Physics, 1990
Electromagnetic casting leads to a mathematical model that consists from electromagnetics coupled with hydrodynamics with one free boundary. This model can be solved by the following proposed algorithm: (1) give an initial meniscus shape, (2) solve Maxwell's equations and compute Lorentz forces, (3) solve Navier-Stokes equations and compute normal ...

Electromagnetism in a gauged chiral model

Physical Review D, 1986
It is shown that the unique addition of electromagnetism to a recently proposed gauged chiral Lagrangian of pseudoscalars and vectors results in the same model as that obtained by the ''hidden symmetry'' approach. The gauge-invariant treatment of ''vector-meson dominance'' is essentially equivalent to the old model of Kroll, Lee, and Zumino but we ...

Electromagnetic Model of K‐Changes

Journal of Geophysical Research: Atmospheres
AbstractK‐changes are observed as step‐like increases in the thundercloud electric fields. The K‐changes occur in the late part of intra‐cloud lightning or during negative cloud‐to‐ground lightning between return strokes. It has been shown that the processes leading to K‐changes initiate in the decayed part of a positive leader channel and propagate ...

Modeling of electromagnetic metamaterials

2010 International Conference on Electromagnetics in Advanced Applications, 2010
Numerical modeling and experiment have the same importance in revealing the unusual properties of electromagnetic metamaterails. On one hand, the numerical modeling can confirm the experiments on metamaterials; on the other hand, it can explore the properties of metamaterials in extreme conditions which cannot be performed experimentally. In this paper,

Modeling of electromagnetic systems

IEEE Transactions on Magnetics, 1991
Modeling techniques are presented for simulation of hybrid (partly electrical, partly magnetic) networks on electrical network simulators. The frequency dependence of the permeability is modeled by a relaxation description, which leads to frequency-independent component values in the network model. The hybrid models can be used for analyses in both the

Electromagnetic Pulsar Models

Publications of the Astronomical Society of the Pacific, 1971
We will briefly review here the general features and predictions of a group of pulsar models which we may class generally as "electromagnetic" models. They are characterized by the supposition that pulsars are rotating neutron stars with strong dipolar magnetic fields, that it is the stress carried by these fields which is responsible for the slowing ...
