A new method to interpolate and extrapolate SAR measurements in a volume in dosimetric experiment

The use of interpolation and extrapolation is necessary in order to allow an evaluation of the electric field components which are not accessible by measurement. Starting from data uniformly or non uniformly spaced, the goal is to rebuild the whole of the signal. A new method to interpolate and extrapolate SAR measurements inside a volume in dosimetric experiments is presented. This technique which is very fast and not very expensive in memory storage is compared with other interpolation methods which use splines or wavelet.
