Abstract:
Electromagnetic fields in time-dispersed media with power dependence are analysed. It is shown that these media have fractal properties. Their fractal dimension is determined. The equations for scalar and vector potentials are found using Maxwell’s equations analogues presented with the help of Caputo differintegral. Electromagnetic fields are numerically calculated in bounded domain for arbitrary functions of charge and current.
Keywords:
fractal electromagnetism, fractional dimention of medium, fractional calculus, time dispersion.
