Gubin A. Microwave response of superconductors at wave incidence grazing angles

Object is a microwave response of superconductors; the aim is an experimental and theoretical justification of possibility to study complex conductivity by p-polarized wave grazing incidence reflectivity measurements; novelty - the method of superconducting materials conductivity investigation was developed using founded features of grazing incidence reflectivity; results - correlation of the bulk melt-textured YBCO sample properties was found in S- and N-states and possibility of sample testing by measurement at room temperature was shown; YBCO film conductivity is measured by the developed method, the fluctuation conductivity was found and accordance with the known 2D model is shown; field of application: research of microwave conductivity could be used both in fundamental physics and for determination of HTS microwave characteristics for the purpose of HTS microwave devices manufacturing.
