Surface impedance of thin graphite films with metallic properties is evaluated by a waveguide technique based on measuring reflection and transmission coefficients of thin film membranes at operating frequencies in rectangular waveguides. One- and two-layer membranes of finite thickness, completely filling the waveguide cross-section, are investigated. Formulas allowing analytical estimates of surface impedances for nonmagnetic films made of amorphous carbon are derived. Simulation results for graphite films at frequencies from 5 to 10 GHz are analyzed.
