Abstract: Complex values of permittivity of general anisotropic materials are manufactured by free- space single- receiver measurement method. The interaction of electromagnetic wave with anisotropic slab is of importance. An application of a grounded anisot ropic slab is included to formulate the expression of reflection coefficient and complex permittivity tensor. The values of reflection coefficient at different incidence angles are calculated and analyzed.

Key words: single- receiver measurement, anisotropic materials, complex permittivty tensor
