| Abstract | A time domain spherical multipole near-to-far-field algorithm running together with a principal component analysis (PCA) signal processing technique is introduced in this paper. Such approach is employed to reduce the near fields obtained by a finite-difference time-domain (FDTD) code that will be used as input to a spherical multipole near-to-far-field transformation algorithm. The technique is applied to obtain the radiation pattern of a half-wavelength dipole, thus validating the code, and also for a configuration of two array dipole. Preliminary results show that when we compare the original signal with the reconstructed using a threshold value of 0.1 the required near-field data is reduced by an average value of 83% for the half-wavelength dipole and also shown that even if the technique is more sensitive in the presence of lobes it can significantly reduce the near-field components. |

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.
