| Abstract | Even the EM simulation tools have had far-reaching progress in last decades [1], the area of high-frequency problems (electrically large problems) [2] seems not be well resolved yet. Technically speaking, the zone of airborne antenna engineering is the most representative one in which an antenna is usually installed on an electrically big platform, say, the airplane itself. In these cases, the airplane is the electrically large electromagnetic scattering body, which will cause reflection field, diffraction field, in addition to the zero-order incident field. PC-borne antenna [3] is supposed to be a new engineering realm of high-frequency problem. In stead of low-frequency method like Moment Method (MM) [4], the Geometrical Theory of Diffraction (GTD) [5] had been thought as the proper one for treating large platform problems. However, GTD is lacking in generality for being developed to be a commercial package. On the other hand, FDTD (Finite-Difference Time-Domain) method [6] has drawn great attention in last decades because of its generality, especially when treating material-inhomogeneous problems. Unfortunately, FDTD is a method of heavy time-consuming and memory-hungry. Thanks to the emerging parallel-computing techniques [7] FDTD has found its new niche for being applied for electrically large antenna problems. By usage of MPI (Message Passing Interfacing) [8], several high-performance CPUs may be employed in the FDTD method. |

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.
