Abstract :
In solving volume integral equations by method of moments with multilevel fast multipole algorithm (MLFMA) acceleration, the memory and time consumption for near group impedance elements calculation is huge, especially for high contrast dielectric targets or multiscale targets. The method of multilevel accelerated Cartesian expansions algorithm combined with MLFMA is employed to enhance the capability of volume integral equations solver. Good performances have been achieved in numerical results.
