In this paper, TR-UWB communication in arbitrarily-shaped boxes with metallic enclosure is rigorously analyzed using full-wave simulations. To be specific, two Maxwell's equations solvers, one based on finite difference time domain (FDTD) and the other the method of moments (MoM), are developed to track electromagnetic wave propagation in the boxes. Impedance boundary condition (IBC) is exploited to model realistic metallic walls. In order to relieve high computational resources requirements, these two simulators are implemented on parallel cluster computers. Results from FDTD and MoM simulators match each other; and they show focusing in both space and time after time-reversal and round-trip propagation operations are carried out onto UWB impulses, which demonstrates the feasibility of TR-UWB communication in boxes with metallic enclosure.
