| Abstract | An assessment of the environmental impact on a communication link is imperative to radio system planning. In this paper simulations have been carried out to investigate the effect of leafy vegetation in the vicinity of communication towers. The leafy vegetation layer is considered to have a flat top surface. The transmitting and the receiving antennas mounted on the towers are at the same height. This height is such that the transmitted signal grazes over the top surface of the vegetation layer at low grazing angles. The leafy vegetation layer is modeled by an ensemble of randomly oriented dielectric discs. Each dielectric disc is characterized by its impedance matrix. Using this impedance matrix as the basis, the scattering from the medium is by vectorially adding up the fields from all discs. Since the vegetation medium is electrically sparse, multiple scattering effects between discs is neglected. |

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.
