| Outline of Final Research Achievements |
A compact power reception and conversion system was studied for wireless power transfer using a high power-density millimeter-wave beam. An incident beam was expanded and then concentrated using a tapered-tube concentrator and beam acquisition efficiency of higher than 90% was achieved. Next, a discharge experiment was conducted by coupling above system with a high power gyrotron. As a result, detonation was successfully driven in the detonation tube. In addition, we proposed a new model in which the critical field for ionization is determined by accumulated electron heating. In simulation, we found nested fine filaments expanding in the electric field direction inside of a primary filament propagating parallel to the incident beam.
