In this paper, we provide a new theoretical model describing mechanism of electromagnetic radiation (and scattering) by passive single-and double-stranded (bifilar) helices. The proposed model is derived from basic physical principles till the end formulas which were computer processed for predicting a polarization type of the wave scattered by a helix. Comparison of the two types of helical oscillators revealed radical differences in their scattering performance (intensity and polarization).
