Abstract
The reflection and transmission spectra of a metamaterial formed by omega-shaped elements with pre-calculated optimal parameters on a silicon substrate have been recorded in the terahertz range at oblique incidence for the s- and p- polarizations of the incident wave. The spectra were interpreted within the dipole radiation theory of electromagnetic waves. Both measurement results and analysis provide evidence sup-porting the presence of a pronounced polarization anisotropy impact in the reflection and transmission of the metamaterial. The potential of these materials to be utilized in the development of devices that control the polarization properties of THz radiation across a wide spectral range is examined.

Changed misprints on pages 5 and 7: p.5 Figure 5 illustrates families of characteristic reflection spectra. Figure 5 illustrates families of characteristic reflection spectra. p.7 l is the omega-shaped element arm length; the resulting reflected radiation is likewise linearly polarized and comprises only an s-component.
