A broad-band technique for determining the electromagnetic properties of isotropic film-shaped materials, which uses a microstrip line, is presented. Complex permittivity and permeability are computed from analytical equations and S-parameter measurements of microstrip cells propagating the dominant mode. Measured ¿¿ and ¿¿ data for several materials are presented between 0.05 GHz and 40 GHz. This technique shows a good agreement between measured and predicted data.
