| Abstract | The effect of the stability factor on the computational accuracy of the time-domain finite-difference method using Maxwell's two curl equations is systematically tested for an initial boundary value problem in electromagnetics. A rectangular waveguide is chosen as the computational domain with matching and reflecting boundaries in two dimensions. The TE/sub 10/ mode is excited as an initial condition. A standing wave envelope is numerically formulated; s/sub max/ and S/sub min/ are sampled as in slotted-line measurements. Simulation results for different values of the stability factor are compared with the value 'unity' of the standing wave envelope in the matched condition. Generally, accuracy is not very sensitive to variations in the stability factor. But better accuracy has been observed at around SF=0.7 than at lower values of the stability factor. For both accuracy and economy reasons the authors suggest that a stability factor close to 0.7 should be chosen.< |

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.
