Problem formulating. Progress in science and technology is inextricably linked with the creation and use of new materials, with the development of techniques for measuring their characteristics. Therefore, the problem of measuring the electromagnetic parameters of materials has been and remains urgent. It should be noted that there are not so many measurement methods, and their capabilities are limited.

Goal. The purpose of this work is to reduce the measurement error of the dielectric and magnetic permeability and the loss tangent of materials by the waveguide method in the frequency range of 8.2–12.4 GHz.

Result. An improved waveguide method for determining the complex permittivity and permeability of materials is described. The verification of this method on the sample of high-resistance silicon showed that when processing experimental data by an improved waveguide method, the error in determining the tangents of the dielectric loss angles tgδε and magnetic loss tanδμ, as well as the real component μ1 of the complex magnetic permeability, is significantly reduced.

Practical meaning. The results obtained allowed to expand the range of capabilities of the waveguide method for determining the electromagnetic parameters of materials.
