The frequency shift of the transfer function of single layer composite materials has been analyzed and tested. The efiects are studied by means of planar pseudo-elliptical fllters in Ka waveguide. The fllters, consisting of a frequency selective surface placed perpendicularly to the waveguide axis, have been realized by a high resolution photolithographic technique. Deviations of the experimental transfer functions from the simulation are analyzed with particular emphasis to the efiect of metal thickness. The flnite thickness of the metal constituting the frequency selective surface causes a shift of the transfer function towards high frequencies (blueshift), attributed to dipole-dipole interaction in the metal layer. Such an efiect is only partially predicted by full wave analysis based on flnite element method. The increase of the thickness determines a reduction of the attenuation for thickness values between 10 and 100 skin depths.
