| Abstract | A new hybrid finite-difference time-domain-mixed potential integral equation method (FDTD-MPIE) is proposed for modeling and simulating multilayer planar problems with possible locally inhomogeneous geometries. By using equivalent principle, the original problem can be divided into different regions. The fields in the inhomogeneous regions are modeled by using FDTD method, which is a time domain method providing broad band fields information. The resultant interaction matrix from FDTD can be used as a look-up table for subsequent model coupling procedure. The fields in the layered structure with possible perfect electric conductors are described in terms of the equivalent electric and magnetic surface current densities by a mixed potential electric-field integral representation with less singular kernals. The interactions between the FDTD model and MPIE model are coupled together by enforcing the continuity of the tangential electric and magnetic fields at the equivalent surface using a Galerkin testing procedure. Numerical results of a canonical test problem are presented to validate the hybrid FDTD-MPIE 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.
