Microwave Heating of Realistic Cylindrical Models of Human Limbs

The distribution of absorbed electromagnetic power density inside arbitrarily cross-sectioned, infinitely long cylinders of biological tissue is analyzed by a method, called the Boundary-Condition-Transfer (BCT) method. The analysis is carried out in the resonance frequency region. The cylinders are illuminated by a TM-polarized (E field is along the cylinder axis) plane-wave or by an infinite line-source, the angle of incidence of the former and the location of the latter being arbitrary. The models presented in this work are composite, non-concentric layered structures which allow representation of the realistic cross-sectional irregularities.
