| Abstract | Methods for the modification and control of currents on electrically long wires have been studied in order to determine the feasibility of using existing structures as efficient radiators. Such radiators would be formed from conducting surfaces present on buildings or other structures, thus providing an additional resource in concealing antennas used for wireless communication. An element composed of dielectric beads has been successfully used to modify the current distributions on electrically long wires, such that the wires radiate similarly to a much smaller element. A simple model of a composite element made up of dielectric beads is presented, and a genetic algorithm is used to design the loading of a 4/spl lambda//sub 0/ wire, such that the radiation pattern emulates that of a half-wave dipole. The simple model of the dielectric beads made it possible to run many simulations of the loaded wire using the GA. The ease with which dielectric bead loaded wires can be modeled suggests that the design of efficient radiators from existing, and more complicated, wire structures is possible. |

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.
