Abstract

Low-frequency electromagnetic scattering from one or more tunnels in a lossy dielectric half-space is considered. The tunnel radii are assumed small compared to the wavelength of the electromagnetic field in the surrounding medium; a tunnel can thus be modeled as a thin scatterer, described by an equivalent impedance per unit length. We examine the normalized backscattering width for cases in which the air-ground interface is either smooth or rough.

Low-Frequency Electromagnetic Backscatter from Buried Tunnels

Casey, K ; Pao, H

This progress report is submitted under a contract between the Special Project Office of DARPA and Lawrence Livermore National Laboratory. The Project Manager at DARPA is Dr. Michael Zatman. Our purpose under this contract is to investigate interactions between electromagnetic waves and a class of buried targets located in multilayered media with rough interfaces. In this report, we investigate three preliminary problems. In each case our specific goal is to understand various aspects of the electromagnetic wave interaction mechanisms with targets in layered media. The first problem, discussed in Section 2, is that of low-frequency electromagnetic backscattering from a tunnelmore »« less

Electromagnetic wave radiation in low frequency range from modulated electron beam antenna in ionosphere

Ohnuki, Shigeo ; Adachi, Saburo

In the previous paper the authors discussed theoretically the electromagnetic radiation in the lower hybrid frequency range from a density-modulated electron beam antenna of finite length injected along the earth magnetic field into ionosphere. It has been predicted for the ground observation that the penetration of VLF whistler waves radiated by the beam antenna into the free space above the ground is possible only in the magnetic equatorial region. This paper discusses theoretically the Poynting power density and wave normal direction for LF whistler waves radiated by the beam antenna of finite length injected along the earth magnetic field intomore »« less
Biological effects of extremely low frequency (ELF) electromagnetic fields: a perspective on the issues

Kavet, R. - Proc. Am. Power Conf.; (United States)

This apper discusses whether health risks are associated with exposure to electromagnetic fields that exist beneath high-voltage transmission lines. This is a question receiving increasing attention as the electric utility industry prepares to supply its customers with increased amounts of electric power. 26 refs.
Low frequency electromagnetic cross-borehole imaging

Pihlman, M. ; Harben, P.E.

Most of the research in cross-borehole electromagnetic (EM) imaging has been done at high frequencies (17 to 200 Mhz). At these frequencies, the propagation distance through-the-earth is limited to less than 8 meters and the attenuation of the signal depends on a complex combination of the earth's conductivity and permittivity. Because of the effect of conductivity and permittivity on the attenuation, the images obtained are difficult to interpret. In this paper, we show that use of frequencies below 2 Mhz theoretically increases the propagation distance through-the-earth, and that the signal attenuation is primarily effected by the earth's conductivity. We developedmore »« less
Interaction of extremely low-frequency electromagnetic fields with humans

Tenforde, T.S.

Public concern has grown in recent years concerning the possible health effects of extremely low-frequency (ELF) electromagnetic fields to which we are exposed in all aspects of everyday life. By definition ELF refers to the range of electromagnetic field frequencies below 300 Hz, which includes the power transmission and distribution frequencies used throughout the world. In materials with the electrical and magnetic properties of living tissues, these fields have a long wavelength (5000 m) and skin depth (150 m). As a consequence, in their interactions with humans and other living organisms ELF fields behave as though they are composed ofmore »« less
