Mechanism of Interaction of Radiowaves and Microwaves with Deoxyribonucleic Acid (DNA)

Abstract

Measurements have been made of the relative permittivity and dielectric loss of aqueous solutions of DNA in the frequency range 1 - 10 GHz. The four types of DNA studied were plasmid, human, xenopus, and calf thymus. No evidence of resonance absorption or enhanced absorption was evident from the behavior of the dielectric data. Extension of the dielectric measurements down to frequencies of a few Hz revealed the existence of dispersion regions caused by ionic motion. Keywords: Microwave resonance; Microwave attenuation; Permittivity; Dielectric loss; Deoxyribonucleic acid.
