Measurements of the propagation of UHF radio wa¨es in two trapezoidal tunnels are reported. Values of propagation loss in dBr100 m are gi¨en. It is found that the propagation attenuates at least 900 MHz. In addition, a portable FM radio system operating at 900 MHz is tested in one tunnel. It achie¨e
## By studying the oscillation profile of numerically generated wave packets. it is found that the patterns of their gray scale maps of local power fluctuations are totally dictated by the group velocity of the wave packet, the phase velocity and the frequency of the central component wave. A meth
