Performance evaluation of active propagation control in a three-dimensional indoor environment

We can improve transmission performance of wireless communications by changing propagation environment actively and appropriately. We call such method "Active Propagation Control" (APC). In the previous studies we showed the fundamental effectiveness of APC by two-dimensional FDTD analysis, assuming an empty room where a metal plate is rotated as a device changing the propagation characteristics. In this paper, we analyze indoor propagation characteristics by using the three-dimensional FDTD method so as to discuss more accurate amount of the improvement of APC in a three-dimensional space. In addition, we change the position of the metal plate besides its size in order to evaluate the effect of the variations on the improvement of APC. In the evaluation, we assume a SISO wireless communication and show the reduction of path loss by APC quantitatively.
