Abstract :
Optimization of a terahertz broadband tabulate metamaterial absorber is presented. We apply the hybrid optimization algorithm, which composes the differential evolution stratega and the continuous anìt colony optimization, to optimize the bandwidth of the absorbing metamaterial. Numerical results show that the optimized absorber has the bandwidth of 0.103THz for the absorptance above 90%.
