| Abstract | This paper considers the integration of three attractive concepts: Electromagnetic Energy Harvesting (EEH), Radio Frequency Identification (RFID) communication, and exploiting the non-linear characteristic of RF devices. An EEH circuit is integrated with a passive RFID tag profiting from three nonlinear phenomena of rectifying elements: (1) the impedance power dependency, (2) the harmonic production, and (3) the RF waveform dependency. The harmonic signals generated by the rectifier section of a commercial 868 MHz RFID chip, and additionally an external modulated signal at the 2.4 GHz ISM band are harvested by rectifier circuit and are used to supply the RFID chip with additional dc energy in order to increase its sensitivity. A prototype is tested and experimental results show the cooperative effect by maximizing the RF-to-dc conversion efficiency of the EEH section (from 40 % to 64 %) and simultaneously enhancing the sensitivity of the RFID chip by 7.2 dB. |

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.
