Transverse electric and transverse magnetic Green's function for coherent and incoherent propagation over a finitely conducting rough surface

Radio Science, 2002

This paper presents wave propagation over a finitely conducting half-space whose surface is bounded by a rough surface of small RMS height. An electric or magnetic current source is used to excite the rough surface, and the Green's function for transverse electric (TE) and transverse magnetic wave propagation is obtained. The appearance of roughness at the boundary produces both a ...


Surface electromagnetic wave in the range of 100–5000 kHz over sea covered by ice (numerical results)

The article demonstrates that the conditions of LF-MF-HF radio wave propagation over the “ice-sea” structure with highly inductive impedance are more favorable than over the sea without ice because of the appearance of surface electromagnetic waves (SEW). It was determined that the conditions of radio wave propagation over ice paths depend on a frequency, ice thickness and distance from the ...

As a result of the interpretation made here, it is concluded that the local phase velocity over a highly inductive surface exceeds ...

  • Transverse electric and transverse magnetic Green's function for coherent and incoherent propagation over a finitely conducting rough surface

    This paper presents wave propagation over a finitely conducting half-space whose surface is bounded by a rough surface of small RMS height. An electric or magnetic current source is used to excite the rough surface, and the Green's function for transverse electric (TE) and transverse magnetic wave propagation is obtained. The appearance of roughness at the boundary produces both a coherent (mean) and incoherent (fluctuating) field distribution, which is obtained from Dyson's equation and Bethe-Salpeter's equation, respectively. The coherent Green's function for vertical polarization exhibits similar characteristics to the Sommerfeld dipole problem where the Zenneck wave pole is modified by roughness. The incoherent field generated by rough surfaces is obtained for both vertical and horizontal polarization, and the conventional cross section per unit length of the rough surface is modified to include the effects of surface roughness. For angles near grazing, a low-grazing-angle cross section is obtained by evaluating the Bethe-Salpeter's equation with the Sommerfeld solution. Finally, the coherent and incoherent intensity for the TE rough surface Green's function is obtained and compared to Monte Carlo simulations.

  • Surface electromagnetic wave in the range of 100–5000 kHz over sea covered by ice (numerical results)

    The article demonstrates that the conditions of LF-MF-HF radio wave propagation over the “ice-sea” structure with highly inductive impedance are more favorable than over the sea without ice because of the appearance of surface electromagnetic waves (SEW). It was determined that the conditions of radio wave propagation over ice paths depend on a frequency, ice thickness and distance from the transmitter within the 100 kHz - 5 MHz range on the paths with ice thickness from 0,6 to 2,7 meters.

  • Analysis of photoelectron effect on the antenna impedance via particle-in-cell simulation

    We present photoelectron effects on the impedance of electric field antennas used for plasma wave investigations. To illustrate the photoelectron effects, we applied electromagnetic Particle-In-Cell simulation to the self-consistent antenna impedance analysis. We confirmed the formation of a dense photoelectron region around the sunlit surfaces of the antenna and the spacecraft. The dense photoelectrons enhance the real part, and decrease the absolute value of the imaginary part, of antenna impedance at low frequencies. We also showed that the antenna conductance can be analytically calculated from simulation results of the electron current flowing into or out of the antenna. The antenna impedance in the photoelectron environment is represented by a parallel equivalent circuit consisting of a capacitance and a resistance, which is consistent with empirical knowledge. The results also imply that the impedance varies with the spin of the spacecraft, which causes the variation of the photoelectron density around the antenna.

  • A note on the groundwave phase velocity over a plane earth

    Equations are derived for the phase velocity of an electromagnetic groundwave propagating over a plane earth having a constant surface impedance. The equations are found to differ in essence from one previously derived by King and Schlak (1967). As a result of the interpretation made here, it is concluded that the local phase velocity over a highly inductive surface exceeds the velocity of light in free space under certain conditions. For strongly capacitive surfaces, the phase velocity is expected to exceed the velocity in free space at all distances. (At the end of this Note, R. J. King and G. A, Schlak provide a reply to the criticisms. Ed.)

  • Electromagnetic diffraction at skew incidence by a wedge with anisotropic impedance faces

    The asymptotic expressions for the total field excited by a plane wave obliquely incident on a wedge with anisotropic impedance faces are represented in the framework of the uniform geometrical theory of diffraction. The problem of decoupling the functional difference equations is solved by applying the perturbation technique on the basis of two analytical solutions: normal incidence and grazing to the edge incidence. The numerical results agree well with those presented in published papers and provide a uniform and continuous behavior of the field dependent upon the skewness of the incident wave outside the wedge region.

  • Diffraction by a right-angled impedance wedge

    A plane electromagnetic wave is incident at an oblique (skew) angle on a wedge of open angle 3π/2 with scalar face impedances, the same on both faces. When the theory previously developed for wedges of arbitrary angle with tensor face impedances is specialized to this case, the analysis simplifies, and the resulting expressions for the geometrical optics, surface wave and diffracted fields are presented. Because of the practical importance of this geometry, a large set of figures is included showing the behavior of the diffracted field for a variety of face impedances.

  • Modeling the effect of the ocean-land interface on induced electric fields during geomagnetic storms

    In this paper a model is developed for the calculation of the enhancement of geomagnetic storm electric fields near ocean-land interfaces. The motivation for this work is the calculation of the electric fields applied to power and telecommunication conductors near the seashore. This model consists of an ocean of depth linearly increasing with distance from the shoreline and a uniformly conducting soil. With this assumption an integral equation is obtained for the electric field for exponentially rising surface magnetic fields. This equation is solved numerically and, for a special limiting case, analytically. Solutions for two different surface magnetic field time histories at the surface are obtained by taking inverse Laplace transforms. Expressions are derived for the change in the electric field when compared with the electric field at the surface of a homogeneous Earth. Numerical examples are given for the enhancement of the electric field for sudden storm commencement and electrojet magnetic field time histories.

  • FDTD surface impedance models for electrically thick dispersive material coatings

    A new accurate finite-difference time-domain model of dielectric and conductive layers on metal surfaces is developed. The model is based on higher-order surface impedance boundary conditions (SIBC). Several improvements to the existing numerical SIBC models are presented. The most important features of the proposed model are the inclusion of the tangential variations of the fields into the model and a considerably more accurate approximation of the impedance function than in the earlier works. In addition to the usual dielectric and conductive layers, the model can also handle layers of Lorentz, Debye, or Drude media. It is shown that the range of applicability of the proposed SIBC model is greatly increased as compared with the earlier models. Verification of the model is performed with one- and two- dimensional simulations. The results are compared with the exact results in both time and frequency domains. Also, a comparison with an earlier model is provided.
