This research used frustrated total internal reflection methods and stimulated surface plasma waves configuration (Kretschmann configuration and Otto configuration). At the same time, we use the surface plasma wave experimental structure of gold, silver, copper metal film thickness changes and carbon dioxide surface plasma wave resonance angle of the computer simulation measurement. The results of this paper are: carbon dioxide in the Kretschmann configuration, gold film thickness of 45 nm, silver film thickness of 60 nm, copper film thickness of 50 nm; In the Otto configuration, gold film thickness of 350 nm, silver film thickness of 600 nm, copper film thickness of 335 nm, There is optimization surface of the surface plasma wave resonance angle.
Keywords: frustrated internal total reflection method, Kretschmann configuration, Otto configuration, surface plasma wave resonance angle, carbon dioxide.
