| Abstract | The wave propagation of magnetostatic surface waves (MSSWs) is formulated in terms of the vector instead of the scalar potential theory. The present formulation of the MSSW propagation accounts for the impact of the finite conductivity of ground planes and dielectric layers and the associated losses in the film stacks. The method can handle the two-dimensional wave propagation in any plane parallel film stack. The complex dispersion equation is explicitly derived for a stack with two ground planes being located at finite distances at opposite sides from the central magnetic film. Numerical results for this configuration are presented. It is shown that the dispersion curves break up into a number of branches and that contrary to the lossless case no maxima and minima with zero group velocity occur. It is shown that the surface-wave like excitations occur within a much wider frequency band than predicted by the standard scalar theory.< |

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.
