摘要:
Further frequency upshift from a DC to AC radiation converter is analyzed and experimentally observed by taking into account the boundary effect of a plasma-filled waveguide. The radiation frequency depends on both plasma density and cut-off frequency of the waveguide. The observed frequencies of the emitted radiation are in reasonable agreement with the expected theoretical values.
