Free Space Analysis of the Scattered Electromagnetic Fields as a Dipole Approaches a Leaky Coaxial Cable.

Abstract

The free space interaction of the near zone electromagnetic fields external to a leaky coaxial cable and a moving dipole is investigated. The method of moments and the equivalence principle are used to find the currents on the dipole and the electromagnetic fields scattered from the dipole. Finally, the overall interaction between these two fields is determined by superposition. The theoretically derived results are then compared with experimental measurements. The findings of this report indicate that exact results are not obtained with a free space analysis; therefore, further work involving electronic intruder detection analysis should include the effects of the earth-air interface.
