simpeg.electromagnetics.viscous_remanent_magnetization.waveforms.StepOff.getCharDecay#
- StepOff.getCharDecay(fieldType, times)[source]#
Return characteristic decay for step-off waveform.
This function defines the decay of the VRM response for the linear problem type. Note that the current will be normalized by its maximum value. The maximum current in the transmitter is specified in the source object.
- Parameters:
- fieldType{‘dhdt’, ‘dbdt’}
Field type. Characteristic decay for ‘h’ or ‘b’ CANNOT be computed for step-off
- times
numpy.ndarray Observation times. These times MUST be during the off-time.
- Returns:
- eta(
n_times)numpy.ndarray Characteristic decay evaluated at all specified times.
- eta(
