| Abstract | The beam mode expansion method is adapted to analyze the radiation of a corrugated conical horn without any restriction due to the balanced hybrid conditions, assuming an hybrid modal (HE$_{11}$)feed. The fields are first calculated on the horn’s aperture and then transformed in a modal expansion. The approximations are discussed and illustrated with computer simulations. Achieved results are finally presented to show the interest of this method.La méthodebme (beam mode expansion) est adaptée à l’analyse du rayonnement d’un cornet cylindrique rainure hors régime d’équilibre hybride, dans l’hypothèse d’une excitation par le mode hybridehe $_{11}$. Le champ sur l’ouverture du cornet pour obtenir une expression exploitable, dans le cas général, est calculé ainsi que le rayonnement dans un formalisme vectoriel multimodal. Les approximations faites dans ces développements sont justifiées a posteriori sur des résultats de simulation. Enfin les résultats que l’on peut attendre de cette nouvelle analyse sont exposés. |

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.
