WebMy current research at Chalmers University is focused on III-V material (GaAs, InGaP) based integrated chip-scale optomechanical (MEMS/MOEMS) systems. My work includes using tools like COMSOL and RCWA for simulation of mechanical and optical properties of micromechanical resonators, process development and optimization in the cleanroom at … WebFor any chosen required precision the RCWA calculation outperforms the FDTD package. The data show that for meta-surface calculations the RCWA method returns results faster than FDTD at the same accuracy. This speed does come at a cost, RCWA is only suited for periodic structures while the FDTD method can also be applied to non-periodic structures.
