| Abstract | In a previous study by Shahir et al., the permittivity profile of object under test (OUT) from electric fields measured outside OUT is accurately estimated by considering the region of interest confined within the boundary of the OUT. This study proposes a continuous-wave multi-view near-field scattering tomography system at the millimetre-wave frequency range and reformulates the sub-space approach for reconstructing the continuous-wave tomographic images while considering the region of interest beyond the OUT boundary. The OUT reconstructed tomographic images enable one to localise the OUT boundaries. The proposed system also eliminates the need for fully systemic isolation (i.e. anechoic chamber) or water as a background medium by reducing multipath effects substantially at millimetre wave. The system performance is evaluated by reconstructing the tomographic images of various samples, and the experimental results are presented. |

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.
