Human buccal cells. The aim of the work: the construction of mathematical models of impulse field in-fluence on biological objects, analytical and numerical investigation of passing, reflection and absorption of ultrawideband fields. Researching the influence of impulse radiation with different pulse duration and power on bioplasts. The method of investigations: solving Maxwell equations taking into account boundary conditions on the surfaces of layered media with losses. Direct numerical solu-tion of Maxwell equation by FDTD. Analysis of cell heterochromatization level. The problems of determining spatial distribution of electromagnetic field of im-pulse wave beam and plane wave in plane layered dielectric medium are solved taking into account losses and dispersion. Solutions in time domain are analyzed for finding the passed power of electromagnetic field. The possibility of determination of layer thickness with sufficient precision by artificial neural network is shown. The experimental investi-gations of buccal epithelium cell heterochromatization under impulse irradiation are car-ried out for different power of electromagnetic field. The analysis of obtained experimen-tal results is performed. The results of investigations can be used for working out the radiolocation, medi-cal and biological devices.
