摘要：

Effective microwave hyperthermia of cancer is proposed by using slightly lossy flat left-handed material lenses. High-resolution focusing of microwave without any auxiliary foci can be achieved in tissue by jointly adjusting the sources behind the flat lenses. Two-dimensional numerical simulations demonstrate that, for tumor of diameter of 0.6 cm immersed in lossy breast tissue, microwave power can be effectively localized in tumor volume and temperature in tumor may be raised to similar to 43.5 degrees C, while keeps below 42 degrees C in the surrounding normal tissue as required in hyperthermia treatment. The proposed T-shaped two-lens system is proved to an efficient scheme for microwave hyperthermia. (C) 2009 Wiley Periodicals, Inc.
