Computer simulation was carried out in the microwave range based on the finite element method for the frequency dependence of the ellipticity coefficient of reflected wave for single-turn and double-turn helices and two-dimensional arrays consisting of the same helices. The possibility of the transformation of the incident linearly polarized electromagnetic waves in a circularly polarized wave reflected from the two-dimensional array on the basis of a single-turn and double-turn helices was shown. Reflected circularly polarized wave is observed at frequencies close to the resonance and doesn’t depend on the orientation of the plane polarization of incident wave relative to the axis of the helices. udKeywords: simulation, transformation of polarization, single-turn and double-turn helices, ellipticity coefficient.
