摘要：

An efficient global optimization approach for a periodic plasmonic nanoslit array based on ex-traordinary optical transmission within an acceptable time range is proposed using Q factor analysis method. The particle swarm optimization is employed as a global optimization tool. The figure of merit is defined as a product of transmission peak value and Q factor. The design variables are the slit width, height, and period of the slit array, respectively. The optical properties such as transmission spectrum and bandwidth are calculated rigorously using the finite element method.
