The uniform theory of diffraction (UTD) developed in Part 1 is used to predict narrow- and wide-band propagation characteristics in tunnels at 900- and 1800-MHz frequencies. Narrow-band propagation characteristics is shown in spatial domain and wide-band propagation in time domain. In empty straight...
