ABSTRACT
The research investigates the mechanism of microwave radiation effects on biological characteristics and structural-dynamic parameters of a sensor bioluminescence system. The research objects are a sterile growth medium (fish meal hydrolisate) and a bacterial culture. It has been established that irradiation causes changes of the growth medium spectral properties within the range of 200-350nm. Changes take place in the intensity and character of luminescence, as well as in relaxation parameters of nuclear magnetic resonance, growth characteristics of the bacterial culture, its cellular morphology and surface topology. The research results enabled us to establish the mechanisms of primary molecular processes that occur when the bacterial culture is exposed to microwave radiation. Transformation of the dynamic-structural state of adsorbed water phases on biopolymer surfaces has been found to be the key factor in the mechanism of microwave effects on living and water-containing objects.

We present a new method for investigation of sensitivity of the integrated optical electrodeless electric field sensor. This method is based on a compact microwave asymmetrical double-ridged waveguide with regular inhomogeneities. Small dimensions of the waveguide along with medium power of the microwave generator produce a strong electric field. The efficiency of the presented experimental unit was verified in the course of testing of the real integrated optical electrodeless electric field sensor (E-sensor).
