For double- and single- layer dielectric structures with increased electroconductivity calculated relations for real and imaginary parts of dielectric permittivity were derived. The absolute values of dielectric permittivity in the range of frequencies from single digit hertz to megahertz were calculated. The range of known materials which can be used as dielectric layers was defined. Based on capacitor structure with paper dielectric soaked in glycerol the change of capacity from fractions of nF to several thousands of nF with change of frequency from 105 Hz to 0,1 Hz was experimentally achieved. Experimental research confirmed correctness of conducted calculated analysis. The advantage of such capacitor in case of passive low-pass filter was shown.
Aim of the work – is the study of possibility of capacitor development with frequency dependent capacity based on structures with increased electroconductivity.

Keywords: single-layer dielectric structures, dielectric permittivity, electrical conductivity of dielectric, migration polarization, electric capacitance, glycerol, electrode system.
