Far-infrared attenuation in glasses
Physical Review B, 1994It is generally accepted that some quasilocal vibra tions (QV) coexist with phonons in glasses at THZ frequencies and it is the excitations that are responsible for the most of unusual properties of these materials. In this paper we study the influence of QV on the far infra-red attenuation A(ω) of glasses.

According to current practice the far-infrared region is considered to be that part of the electromagnetic spectrum between the sodium chloride prism cutoff (about 15 μ) and the wavelengths at which microwave techniques may be successfully employed. The farinfrared region tends to be pushed continually to longer wavelengths by the development of better

Although the far-infrared region of the spectrum (3 cm−1 to 300 cm−1)can be considered today as instrumentally well developed it is still rather difficult to measure absorptivity or reflectivity with high resolution or high precision. This is mainly so because of the lack of powerful sources even though the techniques of spectrometry as well as the ...
