| Abstract: | A novel method has been introduced for measuring the surface impedance of composite material sheets at microwave frequencies. A length of circular waveguide is manufactured using the fibre-reinforced composite material and its scattering parameters are measured with the use of a network analyser (VNA). An iterative simulation method is subsequently used for the derivation of the surface impedance of the composite based on altering the impedance boundary condition on the walls of a precise model of the waveguide, as manufactured, until the simulation results for its scattering parameters match the experimental values. |
