- Opis:
- Investigation of polarizing properties of DNA is chosen as one of primary importance due to mirror asymmetry of the shape of DNA. Preliminary theoretical calculation has shown that the form of DNA is optimum for radiation of a circular electromagnetic wave under the resonance condition (~10 nm). This conclusion has been proved for the metal DNA-like helices in a microwave range in accordance with the principle of scaling. In the given work it is experimentally confirmed the presence of the effect of polarization selectivity in double reflection of microwave waves from DNA-like helical elements depending on their sign (the right-handed and left-handed helices). It is shown that the circular polarization of waves plays an important role in case of interaction of microwaves reflected from the artificial DNA-like structures. Probably, the identical effect takes place in some processes that involve DNA in biological organisms' cells, but in the range of far ultraviolet radiation and the "soft" X-ray range. These results are also interesting in connection with an opportunity of creation of artificial 2D and 3D structures on the basis of branches of a molecule of DNA. Such structures can be into a basis of new type metamaterials.
