| Abstract | Summary form only given. Termination of a magnetically-insulated transmission line (MITL) with an impedance that is less than the matched MITL operating impedance launches a re-trapping wave back up the MITL toward the source. A previous investigation obtained the relationship for the MITL operating conditions (voltage and current) after the passage of the re-trapping wave that depended on the input voltage, the termination impedance, and the MITL operating conditions based on parapotential flow at minimum current. The relationship was in agreement with detailed particle-in-cell (PIC) simulations and experiments of the re-trapping wave process for large area diodes. The scaling law and simulations however were only applied to a constant input (forward going) voltage and termination impedance. This work extends those PIC simulations and wave analyses to MITL operating conditions for termination impedances and input voltages that are functions of time. We first examine the case in which the input voltage is constant and the impedance changes in a staircase manner. These results are then extended to termination impedances that are continuously varying functions of time. The complementary case of fixed termination impedances and a variable input or forward going voltage will also be presented. The MITL operating conditions after the passage of the re-trapping will be examined as a function of the time history of the termination impedance and input voltage. Particle-in- cell simulations will be used extensively in the analyses and compared with linear and non-linear wave analyses. The objective of the work is to determine if the operating conditions of an under-matched magnetically insulated transmission line can be represented by a simple state function or do the final operating conditions depend on the previous time history of the termination impedance and input voltage. |

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.
