The Galerkin method with subsectional linear basis and weighting
functions is used to calculate the low-frequency transverse
electric fields in lossy dielectric cylinders. Arbitrarily
shaped polygonal cells are employed to allow more accurate
modeling of complex objects without excessive matrix sizes. To
demonstrate the validity of the method, the analytical and
numerical solutions are compared for triple-layered concentric
cylinders. The calculated fields in a model of the human torso
exposed to a solenoidal field are also presented. Among other
applications, the method should be useful for evaluating
electromagnetic (em) biohazards, and for analyzing and designing
dielectric antennas and hyperthermia applicators at low
frequencies.
