WebIntroduction - Resonant radiation (RR), often also referred to as dispersive-wave or Cherenkov radiation is a nonlinear optical process by which a soliton propagating in an optical fibre in the presence of higher-order dispersion sheds light through a resonant-like process to a shifted frequency Wai ; cerenkov ; cristiani ; Skryabin ; dudley .This … WebApr 2, 2024 · The rate of the wobbling or precession is the resonance or Larmor frequency. In the magnetic field of an MRI scanner at room temperature, there is approximately the same number of proton nuclei aligned with the main magnetic field B 0 as counter aligned. The aligned position is slightly favored, as the nucleus is at a lower energy in this position.

WebDec 1, 2024 · These efforts have led to the observation of resonant radiation with negative and super-resonant frequencies , and also emitted in the backward direction . In addition, four-wave mixing of solitons and dispersive waves can be generated new frequency [28] , [29] , which plays an important role in the supercontinuum generation. WebSolitons emit resonant radiation (RR) owing to a universal mechanism of phase-matching with linear waves ruled by perturbing higher-order dispersive terms. Well-known examples range from fiber [1,2] to Langmuir plasma [3] or water wave solitons. During the last decade, optical fibers offered the unique opportunity to deepen the physics of RR [4], with …
WebAug 8, 2024 · The new signal is called negative-frequency resonant radiation (NRR), which has been measured in several experiments [12,52,53] and explained by Fabio Biancalana and colleagues using nonlinear optics. The need for both the group- and phase-velocity horizons becomes clear from the dispersion relation in figure 5. WebSchilling CJ.
