| Abstract | A system for time domain polarisation measurements in a wide time range which is based on the well-known Sawyer-Tower method is presented. The time dependent polarisation of dielectric samples is measured after the application of a voltage step. To this aim the voltages on three reference capacitors in series to the sample are measured with different data acquisition systems. During the measurement the capacitors are switched off one after another to avoid self-discharge. In this way the polarisation of the dielectric can be determined in a time range from 10¿6s to 104s, i. e. over 10 decades, with one single run. From these data the polarisation current can be calculated as time derivative of the polarisation. Furthermore, the dielectric permittivity in the frequency domain can be calculated from the data in the time domain by Fourier transformation. Additionally the system allows the measurement of the switching behaviour of ferroelectric samples with a three-pulse method. |

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.
