| Abstract | Certainly, the dip emergence in the resonator with NLE and the decay emergence in the line with NLE are of the same nature. One can see a full analogy between IL(P) dependence for the line and IL) dependence for the resonator with NLE (IL - insertion losses in the dip of AFC dependence). The rapid initial decrease in the dip on AFC dependence for resonators with NLE corresponds to the first step on the IL(P) dependence, obtained for the lines with NLE. Our measurements have revealed the linear dependencies IL and IL(P for resonators and lines, correspondingly (Pin is measured in dbm). The rapid increase of the dip on resonator AFC curves, as well as the rapid increase of the line decay with the input power increase, can be explained by a rapid increase of the NLE surface resistance, caused by its transition from superconducting to the normal state. The heat origin of these effects is supported by observations of hysteretic behavior of the IL(P) dependence, measured in the line with NLE. Coincidence of the critical current density values, obtained from microwave and dc transport measurements, indicate that penetration of microwave induced Abrikosov vortices is responsible for the YBCO film heating and its subsequent transition to the normal state, contrary to the suggested model of Josephson weak links [8]. Calculations, performed in the work [5], show that the NLE transition to the normal state proceeds not abruptly, but through formation of resistive domains, causing strong rise of the line decay, when the input power slightly increases. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
