| Abstract | In coupled-mode analysis, an approximate treatment for radiation modes in open waveguides by equivalent leaky modes in equivalent closed waveguides is presented. The equivalent closed waveguide obtained by enclosing an open waveguide with properly designed PML (perfected matched layer) terminated by PEC (perfect electric conductor) consists of a complete set of orthogonally discrete complex modes. From the solution system of the present equivalent model, a finite number of equivalent leaky modes are chosen to represent the radiation modes to be known according to the condition of phase matching in mode couplings. The coupling with radiation modes is thus treated with the same fashion as that between guided modes and greatly simplified. The equivalent principles and schemes are discussed, meanwhile the effectiveness and accuracy of this treatment is validated by the simulation results of long period fiber gratings (LPG) with an outer cladding of a high or equal refractive index. |

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.
