Title: Low-Frequency Electromagnetic Backscattering from Tunnels

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.

    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 » that is cut into a lossy dielectric half-space. In this problem, the interface between the upper (free space) region and the lower (ground) region is smooth. The tunnel is assumed to be a cylindrical free-space region of infinite extent in its axial direction and with a diameter that is small in comparison to the free-space wavelength. Because its diameter is small, the tunnel can be modeled as a buried ''wire'' described by an equivalent impedance per unit length. In Section 3 we extend the analysis to include a statistically rough interface between the air and ground regions. The interface is modeled as a random-phase screen. Such a screen reduces the coherent power in a plane wave that is transmitted through it, scattering some of the total power into an incoherent field. Our analysis of this second problem quantifies the reduction in the coherent power backscattered from the buried tunnel that is caused by the roughness of the air-ground interface. The problem of low-frequency electromagnetic backscattering from two buried tunnels, parallel to each other but at different locations in the ground, is considered in Section 4. In this analysis, we wish to determine the conditions under which the presence of more than one tunnel can be detected via backscattering. Section 5 concludes the report with a summary of the investigations discussed herein and recommendations for future work on problems of this class.« less

    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 » ionosphere. The power density in the direction of strong peak of radiation inside the group velocity resonance cone angle is calculated in VLF and LF ranges. It is found that the radiation power density in the frequency region a little higher than lower hybrid resonance frequency is extremely intense, and that the one in the LF range for the nighttime of the ionosphere is fairly intense up to f{sub He}/2, where f{sub He} is electron cyclotron frequency, while the radiation power density in the frequency region above f{sub He}/2 is found to become small and to decrease rapidly as a wave frequency increases. The wave normal direction of the maximum radiation measured from direction of the beam antenna is calculated in both VLF and LF regions.« less

    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.

    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 » a new low-frequency cross-borehole electromagnetic system operating between 100 khz and 2 Mhz to see if we could actually transmit 30 meters with an electric dipole antenna. The results of these field trips demonstrated that the electric dipole method of cross-borehole transmission is not feasible for transmission distances of practical interest (30 meters or more) in enhanced oil recovery (EOR) applications. 5 refs., 12 figs.« less

  • 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 » independent electric and magnetic fields components. This paper discusses ELF fields and their interactions with humans and other living organisms as well as their biological effects.« less
