Abstract

Results of millimeter wave (MMW) radiation action on refractive index of 2–10% water solutions of human blood plasma are presented. Investigations were carried out by holographic interferometry. Incident power density of MMW radiation applied was about 10 mW/cm2.

Under MMW irradiation, a refractive index of a 2% solution of human blood plasma was detected to increase by 2.52 × 10″. The field effect leading to refractive index changes was opposite to the temperature effect.

The MMW effect was manifested immediately after the start of irradiation, with the maximum reached after 6–7 min exposure. The initial refractive index was restored 10 min after the generator was switched off.

In this paper the phenomena are explained from the point of view of collective states whose changes take place under MMW field action in aqueous solutions of biomolecules.
