| Abstract | Advances in rapid prototyping using conductive-inkjet and 3D printing, for example, have made the fabrication of antennas and artificial complex media possible. These advances have prompted the need for alternative mathematical methods of analysis that are capable of handling anisotropic and bianisotropic media and also aid in better understanding of the physical nature of electromagnetic fields in complex media environments. As an example, a compact six-vector formalism for Maxwell's equations was developed (I.V. Lindell, A.H. Sihvola, and K. Suchy, J. of Electrom. Waves and Appl., 9, 7/8, 887–903, 1995) that aids in the mathematical manipulation and subsequent solution of problems involving complex media. This formulation can accommodate fully populated material tensors (i.e., all material tensor elements are non-zero), however, the analysis leads to a block 3×3 matrix that requires inversion. If the material property tensors of permittivity and permeability have no transverse-longitudinal or longitudinal-transverse components (i.e., the xz, yz, zx, zy elements are zero), then a four-vector approach can be advantageously employed leading to a block 2×2 matrix which is more easily inverted due to the reduced dimensionality compared to the six-vector approach. In addition, a more compact and physically-insightful form is often achieved for this specialized case of material tensors. If, furthermore, the material property tensors are restricted to gyrotropic media, then a two-vector technique can be readily sought that results in a block 1×1 matrix formulation, which substantially simplifies the analysis and leads to enhanced clarity of the physical nature of the electromagnetic fields. |

| Resource Type | Synopsis |
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.
