| Abstract | A deterministic beam-forming approach aiming at synthesising differently shaped beams for a partial, spherical-surfaced conformal aperture is presented. It is mathematically shown that current distribution on such an aperture can be expanded into a Fourier series, and its far-field radiation pattern can be further expressed in a concise closed form. If the aperture distribution satisfies a weighted zeroth-order or first-order spherical Bessel function, one can easily achieve various shaped beams such as pencil, flat-topped and bimodal beams by simply tuning a single weighting coefficient of the Bessel function. The proposed approach is deterministic and intuitive, making it possible to achieve fast, real-time beam-forming for spherical conformal arrays. |

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.
