Determination of the whole-body absorption cross section of a phantom using RiMAX

The reverberation time has been measured in a reverberation chamber for different loads and for a cross polarized transceiver at the frequency of 1.8 GHz. We determine the whole-body absorption cross section of a canonical phantom using a maximum-likehood high-resolution channel parameters estimator - RiMAX - and good agreement has been obtained with the result from the numerical simulations. The relative error between the simulated values and the RiMAX based measured values is less than 1.3 %.
