| Abstract: | Standing-wave tube with abrupt section(STAS) was a dissonant standing-wave tube whose higher resonance frequencies were not integral multiplies of the first one.Making use of the dissonant property of STAS and through the optimization of the system,extremely nonlinear pure standing-wave field of 180 dB at the first resonance frequency and that of 177 dB at the second resonance frequency have been obtained.At the two resonance frequencies, distortion of waveform and saturation of harmonics were studied exper... |
