An improved algorithm for design of broadband excitation, inversion, and mixing pulse sequences by iterative optimization of phases: TOPS-2
2023, Journal of Magnetic ResonanceFurther analysis of some symmetric and antisymmetric composite pulses for tackling pulse strength errors
2013, Journal of Magnetic ResonanceDual-compensated antisymmetric composite refocusing pulses for NMR
2012, Journal of Magnetic ResonanceCitation Excerpt :Therefore much of the thrust of composite pulse research has been to find sequences which, relative to a single pulse, are broadband with respect to the frequency parameters ω1 = |−γB1| or Ω. Such composite pulses can be said to be compensated for the relevant imperfections [1–18]. Broadband composite 180° pulses have always been of particular interest as both inversion of longitudinal (z) magnetization and refocusing of transverse (x, y) magnetization are very sensitive to the common pulse imperfections.
Improved background suppression in <sup>1</sup>H MAS NMR using composite pulses
2012, Journal of Magnetic ResonanceUse of composite refocusing pulses to form spin echoes
2012, Journal of Magnetic ResonanceCitation Excerpt :It is therefore predicted not to work well as a single refocusing element. A more sophisticated broadband composite 180° pulse is 180°120°180°240°180°120° (designated here TS) [5,8]. This is also designed to compensate for B1 inhomogeneity but also to have an overall rotation axis along the rotating-frame x axis across its usable bandwidth.
