The MECHANEMA, or new method of numerical computation of electromagnetic field intensity at very low frequency range using electromechanical analogies

This paper presents the electric field intensity computation method using analogies between the VLF electric field intensity, obtained from experimental data, and field intensity of a mechanical wave. The method was employed in a Finite Element Method software platform for evaluation. Computations were carried out for different types of wave-guiding media and simulated the VLF environment close to the planet Mars. The results show that the method requires the implementation of a specific model of wave attenuation and may be further modified for different types of antenna radiation patterns.
