The results of the development of an accessible threedimensional electrodynamic model of the human chest in a healthy state and in the presence of various pathologies caused by bronchopulmonary diseases are presented. Simulation and experimental study of the propagation of electromagnetic waves in the human chest has been carried out with the aim of developing high-tech harmless non-invasive methods, devices and automated systems for diagnosing diseases of the bronchopulmonary system based on modern microwave technologies.
