Experimental investigation of the characteristics of the electromagnetic reverberation in the UWB bands

The electromagnetic reverberation time characteristics are investigated at Ultra Wide 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, and shows a resonance phenomena as a function of the frequency. A maximum value of the reverberation ratio of 0.6 is obtained for the investigated scenarios in the room.The electromagnetic reverberation time characteristics are investigated at Ultra Wide Band (UWB) frequencies, i.e., from 2 to 10 GHz.
