Ukrainian Journal of Physics| Резюме: | Conditions for the excitation of surface polaritons in Mg0,2Zn0,8O ceramics have been theoretically analyzed for the first time, and the surface of the disturbed total internal reflection I(ν)/I0(ν) has been plotted, which is a three-dimensional representation of the transmission coefficient in the IR spectral interval. Its dependence on the frequency and incidence angle of radiation is determined. The external reflection IR spectra are measured to calculate the required optical and electrophysical parameters of ceramics using the method of dispersion analysis. The possibility of researching the resonant interaction between optical phonons and plasmons has been demonstrated. The obtained results are in good agreement with the literature data. |
