| Abstract | Two striplines that have identical cross-section and sufficient length difference were used in this investigation as a test vehicle to extract permittivity of printed circuit board. The extraction procedure for Dk and Df follows the algorithm of conventional TRL calibration to firstly extract the frequency-dependent propagation constants of the test vehicle; then the values of Dk and Df at each frequency point are extracted from them by the aids of empirical models of stripline structure. The issue of limited frequency span resulted from numerical ill conditions that generally occurred for TRL-calibration procedure was significantly reduced by introducing sufficient line loss. Increasing the length difference of the test vehicle would introduce more line loss and stabilize the recovering procedure; therefore the extraction bandwidth was immensely increased. Since only two signal-ended striplines are used, this procedure could also save the estate of PCB occupied by the test vehicle, time and cost required for the test measurement. This procedure is also suitable for characterizing temperature-dependent variations of Dk and Df since vector network analyzer calibration is not needed, and un-calibrated S-parameters of the two test lines can be used to correctly extract the permittivity of PCB if proper successive average was applied. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
