Abstract
The investigation of thin film features on high reflectivity materials by optical methods is complicated due to small useful signal. Surface electromagnetic waves (SEW) is considered to be very perspective method for analysis of such materials. For SrTiO3 SEW exist in FIR region (ν=88 - 807cm-1), except narrow gaps, and its propagation distance is about a few millimeters [1,2]. So, it can be easy measured. In the present paper we report the measurements of the optical features of YBa2Cu3O7-x films on SrTiO3(100) substrate by FIR SEW amplitude and phase spectroscopy at temperatures 80 - 300K.
