| Abstract | Summary form only given. FOA has together with Chalmers University started a research effort to theoretically and experimentally investigate the physics of high power microwave (HPM) breakdown in slots, with the goal to gain understanding of microwave breakdown tail erosion effects in slots and associated microwave carrier frequency conversion. Microwave breakdown phenomena have previously been studied at FOA and Chalmers. In this paper, experimental results of HPM breakdown in slots are presented, for plane wave HPM illumination towards metallic plane sheets with slots of various geometries. The HPM source used was a 37 GHz BWO capable of generating 15 MW in 4 ns pulses. The incident microwave electric field strengths have been measured using a hot electron detector, which also was used to measure the tail erosion effect of the pulse partially absorbed by the microwave breakdown in the slot. It was found that the threshold for the incident field to cause breakdown is higher the wider the slot, as expected due to the field enhancement effect. Statistical effects on the microwave breakdown in the slots have also been observed, in the sense that the breakdown happens only for a few of the incident pulses. |

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.
