Abstract :
To obtain deep and local hyperthermia in the microwave region, lens applicators for concentrating electromagnetic energy in a lossy medium such as human muscle are presented. The applicators are a direct-contact metal plate lens and a partially dielectric-filled waveguide lens. Electric field and heating simulation with phantom modeling of human tissue shows that the heating depth is over 50 mm using the lens applicator at microwave frequencies.<>
