| Abstract: | Measuring optical parameters of a negative-refractive-index film with a prism coupler is presented theoretically at the first time.The measuring principle has been given.The rigorous theoretical model of a prism coupler system is also given.The propagating matrix method is used to simulate the prism coupling system to prove the method presented.The influence of the gap between the prism and negative-refractive-index film on the measurement is both theoretically and simulatively studied. |
