| Abstract | To calculate the scattering from thin dielectric-coated perfect electric conductor (PEC) surfaces, the impedance boundary conditions (IBC) and thin dielectric sheet (TDS) approximation are quite powerful in integral equation method because both remove the need to solve the field in dielectric layer. However, the rigid validation criteria restrict the application scope of IBC method. Although the TDS approximation removes physical restrictions by basing on the rigorous integral formulation, only electric material coating have been considered in available literatures. This paper gives an introduction of our progress in the calculation for dielectric-coated PEC surfaces with thin dielectric approximation, including the hybrid PEC-dielectric formulations to deal with the coating with electric and magnetic materials; the multi-layer TDS approximation to analyze coatings with relatively large thickness; the utilization of phase extracted basis functions for electrically large and smooth PEC coatings and some special treatments near the edges to account for the singularity currents for open PEC surfaces. |

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.
