| Abstract | The authors present an algorithm called the nested equivalence principle algorithm (NEPAL) to solve volume integral equations with computational complexity of N/sup 1.5/ in two dimensions and N/sup 2/ in three dimensions. The principal idea of this approach is to nest one algorithm within another so that a smaller problem is solved before a larger one. The size of the problem increases by a factor of 2/sup n/ at each stage where n is the dimension of the problem. In this manner, an N unknown problem is solved in log/sub n/ N steps. The authors have implemented NEPAL to solve volume integral equations and compared the results with the direct solution of the volume integral equations by the method of moments. The results are in good agreement for both E/sub z/ and H/sub z/ polarized waves. The authors have also studied the growth of computer time with the number of unknowns in the problem and found that NEPAL is very competitive with RATMA.< |

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.
