Global Minimum Peak RF Design for Large Time-Bandwidth Saturation Pulse

Christine Law¹, Sonal Josan²

We demonstrate a convex optimization technique to design minimum peak RF saturation pulses. This method achieves global minimum peak RF amplitude without the need of exhaustive search over possible phase profiles. Our technique accept passband/stopband ripple and time-bandwidth product as inputs. But to formulate as a convex problem, we make use of autocorrelation function of the rf waveform and employ the technique of convex iteration. We compare our technique with exhaustive search in small time-bandwidth case and show a result for large time-bandwidth design.
