Mathematical methods for analyzing the results of investigation of dielectric

One of the most informative methods for studying dielectric materials is the analysis of their polarization and depolarization processes. The most suitable representation is the dielectric diagram in the complex plane (Argand diagram). Often, the dielectric diagram is represented as a collection of intersecting parts of circles, at least for preprocessing. The paper proposes means of modeling the dielectric diagram by means of a set of parts of circles.
