| Abstract | Radiation from a linear array oscillator with a spiral antenna has been coupled out of the dewar through a Teflon window. Both its linewidth and its power have been measured after coupling the radiation through free space into a second dewar. The linewidth has been determined using a SIS mixer with a spiral antenna which was pumped with an 88 GHz phase-locked Gunn oscillator, and also by Josephson mixing of the array itself. The array oscillator has a distributed array structure of 300 resistively shunted junctions which are placed in groups of 6 junctions. It was fabricated on a silicon wafer and has a two-arm spiral antenna. The chip was attached to a silicon lens with an anti-reflection coating. The linewidth of the array oscillator was determined between 158 GHz and 194 GHz, far below its design frequency of 400 GHz. The measured linewidth and power data of the oscillator reveal interesting information about its phaselocking behavior in the operating range far below its design frequency. |

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.
