Abstract:

The application of computational electromagnetics (CEM) to problems concerning electromagnetic fields (EMF) of radiofrequency (RF) and the human body dates back to the early 1970s. The methods used in those days were often analytical or semi-analytical and applied to simplistic structures representing the human head and body, such as homogeneous or layered circles, cylinders, and ellipsoids. Numerical methods were later used for simpler models representing the tissue, such as the Finite Difference Time Domain Technique, the Finite Element Approach, and Integral Equation Techniques. The goal then (and now), It was to measure the fields from an RF source penetrating the human head/body. The biological effects of the RF fields can be studied with this quantification. Complete wave techniques are the subject of this contribution to numerical techniques in RF dosimetry. The FDTD, MoM, and FEM will be discussed in particular. The FDTD approach is the most common and commonly used technique by far.
