## ABSTRACT

EM dosimetry, i.e., measurement or calculation of the EM radiation absorbed by humans in radiation fi elds, has become increasingly important as the use of EM devices in our society has increased. Additionally, dosimetry considers the measurement or determination by calculation of induced current density, specifi c absorption (SA), or SAR distributions in objects like models (phantoms), animals, humans, or even parts of human body exposed to EM fi elds [1,2]. At lower frequencies (below ∼100 kHz), many biological effects are quantifi ed in terms of the current density in tissue, and this parameter is most often used as a dosimetric quantity. At higher frequencies, many (but not all) interactions are due to the rate of energy deposition per unit mass. This is why SAR is used as the dosimetric measure at those frequencies [3].
