Assessment of permittivity of composite nanomaterials using a microstrip interdigital resonator in the super high frequency range
Mathematical modeling of the microstrip line structure with a microstrip interdigital resonator has been done in the microwave range. Optimal settings in the short-wave region of the microwave range were chosen. Electrical parameters of this interdigital structure with thick-film samples of materials with dielectric constant from 0.1 to 10 were described. Determining dielectric constant of composite nanomaterials in the microwave range using interdigital structure was shown. Microstrip samples were fabricated and measurements of the real part of the dielectric constant of a polymer composite nanomaterial based on matrices of the low-density polyethylene and polymethylmethacrylate were carried out.
