Contactless measurement of electromagnetic parameters of nanomaterials

Abstract

This paper describes the theoretical justification of operative contactless measurement of electromagnetic parameters of nanomaterials, based on probing of the controlled 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 procedure is given, and the technique of search for the desired parameters based on measuring the amplitude and phase of the reflected signal with further solution of the nonlinear system of algebraic equations is developed.
