Parallel FDTD Modeling of a Focal Plane Array with Vivaldi Elements on the Highly Parallel LOFAR BlueGene/L Supercomputer

This paper describes some preliminary results of a numerical study towards the modeling of a focal plane array (FPA) with Vivaldi elements, carried out on the LOFAR BlueGene/L, a supercomputer with more than 6000 nodes located at the University of Groningen. The parallel finite-difference time domain (PFDTD) code was used to simulate the array because it is able to achieve very high efficiency on such parallel computers
