Electromagnetic Simulation of MEMS-Controlled Reflectarrays based on SCT in Grid Environment

Abstract : The SCT-based simulation tool consists of a MATLAB code developed to run on a single machine in order to predict the phase-shift for all possible MEMS configurations. The 1024 configurations of a phase-shifter cell are obtained by the UP/DOWN positions of the 10 RF MEMS switches inserted in the slit of the 3 metallic patches (Legay, 2005). This problem represent a very computational demanding task on stand alone machines. In this work we report how parallel distributed computing in grid environment offers a very suitable tool for this specific problem. The multi-port networks are computed on GRID5000 nodes and it has yielded a 90.5% of simulation time reduction while keeping the same accuracy for the several frequency values we have tested.
