NUMERICAL SIMULATION OF ELECTROMAGNETIC SYSTEMS OF SPECIMEN POSITIONING IN MICROWAVE RESONANCE SENSORS WITH COAXIAL MEASURING APERTURE
ABSTRACT
The results of solving the problems of non-contact microwave diagnostics of biological systems based on the relationship between the effective dielectric constant biological specimens with its molecular structure and content of free or bound water are considered. To reduce the volume of patients clinical trial in the diagnosis and choice of treatment of cardiac pathologies ways it is proposed to use a quarter-wave coaxial resonator sensors of measuring aperture, which is placed in the bio sample field under study. Modern analytical and numerical methods for solving such systems have high accuracy, and allow creating of efficient methods of theoretical calibration. The comparison carried out on the basis of numerical and analytical models of the open and closed systems of placing the sample for designs with an air gap and without it, as well as ways of generating information yielded quantitative and qualitative representation of the ratio required in practical diagnostic systems.
