A method and apparatus for non-invasive hyperthermia is described employing an electromagnetic (EM) energy generating applicator which utilizes in one embodiment an artificially simulated impedance matching layer for coupling energy to tissue. In another embodiment, the matching layer is comprised of varactor diodes and is voltage controllable. In another embodiment, the applicator utilizes a voltage controllable trough-guide applicator and, lastly, a combination ultrasound and EM applicator is described.
