“…Microwave imaging system operates by observing contrast in the dielectric permittivity of various parts in the imaged objects and their surroundings. The microwave imaging technique is used for the examination of different tissues and organs of a patient: imaging of breast cancer [25,26], brain stroke diagnostics [27][28][29], microwave bone imaging [30][31][32][33][34][35], etc. In all cases mentioned, the multilayer dielectric medium is investigated.…”
