Outline of Final Research Achievements

We carried out the research on the application of negative-index meta-material in the development of radiation sources with low energy electron beam. A new theory was presented to correctly describe the beam-wave interaction and the process of electromagnetic wave radiation. The theory was used to study the characteristics of electromagnetic wave induced from negative-index meta-material, and we found that some modes are possible to interact with the low energy electron beam. Based on this, a Cherenkov oscillator without external reflectors was studied. Finally, some types of negative-index meta-material were designed.
