| Abstract | Summary form only given. Low pressure (<5 mTorr) electron cyclotron resonance (ECR) sources are being developed for downstream etching and deposition, and production of radicals for surface treatment. The spatial coupling of microwave radiation to the plasma in these systems is a concern due to issues related to the uniformity of dissociation, electron heating, and ultimately process uniformity. To investigate these issues, we have developed a finite-difference-time-domain (FDTD) simulation for microwave injection and propagation. The FDTD simulation has been incorporated as a module in the 2-dimensional Hybrid Plasma Equipment Model (HPEM). Plasma dynamics are coupled to the electromagnetic fields through a tensor form of Ohm's law. During each iteration through the model, the FDTD simulation uses a leap-frog scheme for time integration, with time steps that are 30% of the Courant limit, until reaching the steady state. Power deposition calculated in the FDTD module is then used in solving the electron energy equation. The system of interest uses circular TE(O,n) microwave mode fields injected along the axis of a cylindrically symmetric downstream reactor. |

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.
