Abstract :
Flat left-handed metamaterial (LHM) lens shows great potentials for superficial tumor hyperthermia. In clinic, superficial tumor may occur in a considerably large area, and take different shapes. For such superficial tumors, joint heating by using multiple sources are desired for effective hyperthermia. In this paper, it is demonstrated by numerical simulations that by properly arranging the positions of the sources, the heat region in tissue characterized by heating temperature above 42°C can be enlarged properly.
