Abstract
This paper describes the theoretical justification of operative contactless measurement of electromagnetic parameters of nanomaterials, based on probing of the test surface with an electromagnetic signal with subsequent processing of the reflected signal. The electromagnetic properties of these materials are determined by dielectric and magnetic permeability and specific electrical conductivity. The mathematical description of the measurement is given, and the technique of searching for the desired parameters based on the measurement of the amplitude and phase of the reflected signal with a further solution of the nonlinear system of algebraic equations is developed.
