The differ-integral properties of contours and surfaces in millimeter-wave band

Fractal properties of substance and bounded regions of space are especially become important in microwave region (millimeter-waveband), when the size of material structure roughness become comparable with length of a wave. In this paper we define multifractal measure associated with the distribution of a current on the geometrical storage and demonstrate a possibility of definition such measure by differ-integration calculus. The main object of our work is numerical decision of practically important problems, such as magnetic field determination for the fractally distributed current in real conductors.
