The absorption and reflection spectra of composites synthesized on the basis of magnetic liquids with the addition of conductive nonmagnetic particles under the influence of a constant magnetic field have been experimentally studied. The measurements were carried out on the main TEM mode of a coaxial waveguide in the frequency range of 10-18 GHz. To interpret the results obtained, numerical modeling of the system under study was carried out in the approximation of an effective medium using the finite element method.
