Abstract :
This paper discusses the modeling of an indoor electromagnetic testing range. The large size of the range makes FDTD simulations difficult on traditional workstations and desktop computers. An efficient out-of-core algorithm (OoC) is used to swap a portion of the FDTD space efficiently to magnetic storage without significantly impacting run times. Additionally, the indoor range uses a large planar phased array (256 elements) to provide source excitation. Backscatter returns are simulated in FDTD and compared to actual measurements.
