| Abstract | Integral equation domain decomposition method (IE-DDM) is a very effective method for multi-scale time-harmonic electromagnetic problem. IE-DDM can improve the ill-conditioned matrix of the multi-scale problem, yield rapid convergence in the Krylov iterative solution process. In this paper, we use the Inner-Outer Krylov iteration technique to solve the matrix more stably by employing the DDM as an effective pre-conditioner. To speed up the computations of the sub-domains, a recycling Krylov subspace method GCRO with deflated restarting (GCRO-DR) is used. at the same time, the sparse approximation inverse (SAI) precondition technique is also applied to achieve fast convergence. Several complicated multi-scale cases are investigated to demonstrate the validity and ability of the present 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.
