Efficient and accurate EM simulation of large array antennas and imaging systems

Computational techniques have reached a level of maturity which enables their use for large and complex applications. This paper introduces a new XPU calculation technique (software accelerated computing on modern CPUs) which speeds up Finite Difference Time Domain (FDTD) simulations on modern consumer PCs and server workstations. This allows the usage of the 3D full wave FDTD method for accurate simulations of large array antennas and imaging systems. It is shown that the XPU simulation technique outperforms comparable state-of-the-art GPU-solutions by a factor of about 2.5 in simulation speed and by a factor of >; 8 in maximum simulation size.
