Fullwave analysis of reflectarrays on double Iso/Anisotropic layers

This work presents a fullwave analysis of reflectarrays composed by a rectangular array of square conducting patches impressed on a grounded substrate with two uniaxial anisotropic layers. The analysis is performed in the spectral domain by using the Green’s function technique in combination with the Galerkin method. Numerical results are presented for reflecarrays impressed on iso/anisotropic substrates. For the particular case of reflectearrays on isotropic layers, agreement was oserved with results available in the literature.
