Paper Abstract

For the air-ZnO-Si02 system (dZnO ~0.1-10μ, 400-600 cm-1 spectral region) we show that there exist three branches of surface polaritons (~420-430, 470-520 and 520-570 cm-1), the first of them being weak for all dZnO. For model medium instead of Si02, one of two SP branches which one has for ZnO film in air gradually transforms to two branches. The calculations predict wave-guide branches in both p- and s-polarizations below 420 cm-1. For the air-Ge-BeO system (dZnGe ~0.1-10μm, 600-1200 cm-1), deposition of Ge allows one to move the SP absorption away from the frequency of CO2 laser (960 cm-1).
