Abstract: A method and system for selective heating of an object based on a model of the object, the method comprising the steps of: modeling of a wave front of a source, which wave front is propagated through the model object from a virtual antenna placed in the model of the specific region where heating is desired, simulating a radiated field and measuring the same using computer models of surrounding antenna system, time-reversing, transferring and synthesizing the signal in a real system, transmitting by a real antenna system the field in a time reversed order, and refocusing of time reversed signal at the original s the invariance of a wave equation under time reversal.
