"Multi-frequency improved constant amplitude pulses for broadband inversion"
Douglas Brown, Magn. Reson. Chem. 2008, 46, 1037-1044.



All shapes are in Varian format and optimized for 18kHz, or the power needed to produce a 13.9us hard pw90. They can be scaled linearly, less power = longer duration with lower bandwidth. So if your pw90 is 20us, at the same power use the MICA duration * 20/13.9 and effective bandwidth will be MICA bandwidth *13.9/20. Naming convention: MICA180 = Constant amplitude inversion pulse, MICA180T = Constant amplitude inversion pulse with linear truncation at 10% of ends, MICA180R = Constant amplitude refocusing pulse. Example: MICA180-120-40 - MICA180 pulse, 120us duration, optimized over 40kHz bandwidth (at 18kHz field). Some time reversed versions are included for CRISIS experiments.
