The electromagnetic reverberation time characteristics are investigated at UltraWide Band (UWB) frequencies, i.e., from 2 to 10 GHz. The reverberation time is bandwidth independent and decreases as the frequency increases. Besides, the reverberation ratio - the contribution of the diffuse fields in the total power - is addressed as well. The reverberation ratio increases also with larger Tx-Rx separation,...
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...
Experimentally assessing the whole‐body specific absorption rate (SARwb) in a complex indoor environment is very challenging. An experimental method based on room electromagnetics theory (accounting only the line‐of‐sight as specular path) is validated using numerical simulations with the finite‐difference time‐domain method. Furthermore, the method accounts for diffuse multipath components (DMC)...
