Abstract :
Suitable Green´s dyadics are determined for the fields generated by a surface current density in a plane parallel to the interface of a layered isotropic structure. Special care is taken to ensure that Green´s function can still be calculated in the source region by circumventing the numerical problems using analytical procedures. The obtained Green´s function is used to calculate the power deposition from a microstrip antenna inside a layered biological tissue, the media involved can be highly lossy. An analytical method is developed to avoid numerical problems arising from the exponential decay of the fields due to these losses
