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...
In this paper, we have demonstrated a technique in which the photonic bands of two-dimensional triangular lattice photonic crystal slab waveguides can be statically tuned by nanoscale modifications, thereby enabling unprecedented adjustment to the dispersion properties of any 2D photonic crystal. Additionally, the technique facilitates the formation of layered and composite 2D PC waveguides thus opening...
