Abstract | A novel approach is introduced for measuring the shielding effectiveness in resonant conductive enclosures having apertures in a removable side wall. The measurement setup was based on GTEM cell as a compact field-generating environment, capable of accommodating small enclosures as DUTs. The signal was fed into the GTEM cell, thus creating a controlled incident field impinging on the enclosure. The field level inside the exposed enclosure was collected as the output signal. Shielding effectiveness was calculated as the ratio of the S21 parameter measured without the side wall attached to the enclosure, to the S21 parameter measured with the side wall attached, both averaged over the full rotation of the stirrer. Highly expressed resonances were attenuated by introducing the mechanical stirring into the enclosure, thus turning the inside of the enclosure into a reverberation chamber. Additionally, the resonant behavior of the enclosure was reduced by introducing the water containers within the enclosure volume as dissipative load, consequently lowering the enclosure Q factor. The results were in excellent agreement with the ones previously obtained using mode stirred technique. |

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.
