| Abstract | Integrated structural-electromagnetic design is one of the current research hotspots in the area of antenna design. In this letter, a mesh refinement method of structure finite elements is developed to produce electromagnetic grids by constructing a quadratic surface over each element. To begin with, the normal vector at each grid node is constructed through the linear combination of normal vectors of the elements around that node. Then, with the help of the constructed normal vectors and grid node coordinates, a quadratic surface is determined over each element to be the approximation of the curved reflector. Lastly, the refinement of structure elements is performed on quadratic surfaces. Simulations are performed with good results. The proposed method can reduce grid discretization error (GDE), improve the accuracy of numerical integration of the far field, and decrease the total number of structure elements. |

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.
