In this paper, we present a hybrid of genetic and gradient-based algorilhms, which eflciently find the global optimum without getting stuck at local minima, for iterative microwave inverse scattering(lM1S). It utilizes the global convergence of genetic algorithm(GA) and fine local tunability of gradient-based algorithm through alternation so as to $nd(More)
Visual simulation using computer graphics and virtual reality has come to be used recently in the production process to enhance the quality of materials and products. In this paper, we propose a simulation of multilayer thin-film interference for pearl material preproduction such as cosmetic development. Pearls manifest a very specific optical phenomenon(More)
