Abstract

Artificial neural network and simulated annealing are applied to obtain optimized design parameters of skewed omega-shaped metamaterial unit cells for providing left-handed material (LHM) with a negative refractive index. The implemented numerical and experimental methods provide evidence for the validity and practicality of the technique. Simulation, with optimized parameters, using CST Microwave Studio, shows that skewed LHMs are low-loss materials.
