Abstract | An approach which attempts to combine the advantages of both the IML (impedance matrix localization) and the MMP (multiple multipole) methods is introduced. The strategy followed in this method is to expand the scattered fields in terms of beams, generated by a judiciously selected set of multipole sources located in the complex space. The method can be viewed as a numerical approach to finding an approximate Gabor representation of the boundary field. Since the completeness properties and other characteristics of the Gabor expansion functions are well understood, the task of developing a set of simple rules for choosing the orders and locations of the multipoles is greatly facilitated. And yet, in common with the IML and MMP methods, the present approach retains the advantage in terms of the number of unknowns over the MoM, as it typically uses less than four unknowns per wavelength. The formulation presented here has been employed to solve the problem of scattering by a variety of cylindrical shapes.< |

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.
