| Abstract | A type of superconducting receiving element comprising a complementary spiral antenna and a series-parallel superconductor-insulator-superconductor (SIS) array with individual tuning of each SIS junction has been designed, fabricated, and experimentally studied. The array was designed for the 80-160 GHz waveband and consists of five SIS junctions, each with a 1.5- mu /sup 2/ area, six inductive short-ended slotlines, and two decoupling capacitances. The effective direct detector bandwidth of this structure with a quantum efficiency equalling unity has been estimated to be as wide as 70 GHz. The noise temperature of the heterodyne mixer has been measured in a three-lens Gaussian beam guide by means of the hot/cold load method, yielding a receiver DSB noise temperature of 80 K. The intermediate-frequency (IF) mixer port load bandwidth and the effect of thermal background radiation on the I-V curve and the saturation of the SIS mixer have been studied.< |

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.
