{"product_id":"9781598295351","title":"Electromagnetic Scattering Using the Iterative Multiregion Technique","description":"\u003cp\u003eIn this work an iterative approach using the finite difference frequency domain method is presented in order to solve the problem of scattering from large scale electromagnetic structures. The idea of the proposed iterative approach is to divide one computational domain into smaller sub-regions and solve each sub-region separately. Then the sub-region solutions are combined iteratively to obtain a solution for the complete domain. As a result, a considerable reduction in the computation time and memory is achieved. This procedure is referred to as the iterative multi-region technique (IMR). Different enhancement procedures are investigated and introduced toward the construction of this technique. These procedures are: a) a hybrid technique combining the iterative multi region technique and a method of moment technique is found to be efficient in producing accurate results with a remarkable computer memory saving. b) The iterative multi-region technique is implemented on a parallel platform that led to a tremendous computational time saving. c) Together, the multi-grid technique and the incomplete LU preconditioner are used with the IMR technique to speed up the convergence rate of the final solution, which reduces the total computational time. Thus, the proposed iterative technique in conjunction with the enhancement procedures introduces a novel approach to solve large, open boundary, unconnected electromagnetic problems in an efficient and robust way.\u003c\/p\u003e","brand":"Morgan \u0026 Claypool Publishers","offers":[{"title":"Default Title","offer_id":47041273561328,"sku":"9781598295351","price":40.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781598295351_p0.jpg?v=1763825399","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781598295351","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
