| Abstract | The modified frequency-domain method is used to simulate the photonic properties of triangular-arrayed rods which are surrounded with air and possess non-unity dielectric /spl epsi//sub rod/ and magnetic permeability /spl mu//sub rod/ functions. It was found that the photonic band gap becomes broader for the TE mode when materials with higher magnetic permeability and lower dielectric permeability are used for rods as compared to that of purely dielectric rods with the same refractive index of rods n/sub rod/(= /spl epsi//sub rod//sup 1/2//spl mu//sub rod//sup 1/2/ ) whereas the gap is reduced for the TM mode. We then further examine the photonic characterizations of the photonic-crystal cavity, wherein a point defect is introduced into the triangular-arrayed rods. Under a fixed n/sub rod/, the resonant frequency of the TE mode in the first band gap is lower and electromagnetic energy concentration at the point defect is higher when materials with higher magnetic permeability and lower dielectric permeability are adopted for rods. But opposing results are obtained for the TM mode. All the details will be discussed. |

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.
