Abstract | A new approach to the theoretical study of the electron beam-wave interaction in arbitrary RF structures is presented in this paper. In any such interaction system, there are two coordinate systems: the lab system; the rest coordinate system for the plasma, if it exists; and the moving coordinate system for the electron beam. Both the electron beam and the plasma are considered special media with different characteristics. The permittivity tensor and the permeability tensor can be found in the moving coordinate system for the beam while that for the plasma can be found in the lab coordinate system. Then, making use of the transformation of electromagnetic fields in Minkovski space and the Lorentz transformation of the 4D wave vectors, all the physics quantities in the moving coordinate system can be transferred into the lab coordinate system. Then the Maxwell's equations with the transferred constitutive tensors should be used to derive the desired dispersion equation. This new approach is a very efficient and accurate method for the study of electron beam-wave interactions. |

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.
