| Abstract | Summary form only given, as follows. A new idea for the guiding of electromagnetic radiation by a plasma is presented. The scheme uses the magnetic field dependence of the index of refraction of in a magnetized plasma. An external DC axial magnetic field that varies with transverse position induces a transverse variation of the index of refraction of an electromagnetic wave propagation in the axial direction. The concept is similar to laser guiding in a density channel, but differs in that the plasma is now homogeneous and gradients are obtained by variation of the external fields. Using standard theoretical techniques employed in laser-plasma interactions, an equation for the evolution of the transverse size of the wave can be obtained. The equation relates the gradient in the magnetic field with the size of the guided electromagnetic wave. Two-dimensional XOOPIC simulations compared with theory. A further extension of the concept envisions using the cyclotron resonance in the dispersion relation to generate a highly localized steep gradient in the index of refraction. The resonance region acts as barrier to the wave in this magnetic waveguide. The theory is tested in a XOOPIC run using a planar magnetic wiggler field. The field model has transverse and axial fields, satisfying Maxwell's Equations, with exponential increases transversely and sinusoidal variation in the axial direction. Simulations clear demonstrate the validity of the concept. |

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.
