摘要
Measurements were made of the reflection and transmission of lambda equals 0. 8 to 4. 2 mm radiation at temperatures from 25 degree C to 75 degree C for vanadium dioxide films. The experimentally determined reflection and transmission coefficients were used in a calculation of the complex permittivity, refractive index, extinction coefficient, and high-frequency conductivity. The results of these microwave measurements were compared with those obtained under dc conditions. It was concluded that in the millimeter range, the electrodynamic properties of the investigated material could be described by the classical dispersion relationships. The metal-semiconductor phase transition in this material, accompanied by abrupt changes in the electrical and optical properties, has a number of promising applications in display, conversion, and holographic recording.
