The simulation of spin echo excitation by pulses with arbitrary modulation

Abstract

The method of solving the equations of motion of the magnetization vector in a pulsed magnetic field with arbitrary modulation based on stepwise approximation of the complex envelope. Using this method simulated excitation of spin echo signals from pulses of the amplitude-frequency and amplitude modulation.
