FIELD: radio measurements of low-impedance dielectric materials at microwave frequencies, in particular, measurement of the complex relative permittivity and the loss tangent of a dielectric of composite materials characterized by high values of complex relative permittivity and conductance. ^ SUBSTANCE: measurements are taken with the aid of a waveguide standing-wave resonator, the values of the complex permittivity are determined by the measured values of resonance frequency, attenuation and quality factor. ^ EFFECT: enhanced precision of measurement of the value of the complex permittivity of low-impedance materials at microwave frequencies, having high values of complex permittivity . ^ 2 cl |
