In present work we introduce a measuring device that can be used for investigation of the spectral parameters in resonant microwave systems with high Q factor. The device consists of a microwave generator (G4-142), a control unit, a system of data collection, processing, and transition, PC and software for working with obtained data. Testing measurements in open resonators with dielectrics are also presented.

Isolated human buccal epithelium cells were irradiated by microwaves of frequency f = 36.64 GHz, surface power density E = 10-2, 10-1, and 1 W/m2, exposure time 10 s. The state of cell membranes was evaluated by the method of vital indigo-carmine and trypan blue staining. The percentage of unstained cells after irradiation at E = 10-1 and 1 W/m2 decreased as a result of the microwave radiation exposure indicating an increase in cell damage or death. The left-hand polarized radiation caused greater cellular damage than the right-hand polarized radiation.

The maximally realistic method of estimation of higher derivatives of Doppler frequency on the basis of coherent pulse group due to its partitioning has been developed. Dependencies of time of optimization and probability of anomalous errors as functions of a number of fragments, parameters of the pulse group and signal-to-noise ratio have been obtained. The optimal number of fragments has been found. The obtained results have been verified with the simulated data.
