simpeg.electromagnetics.time_domain.sources.RampOffWaveform#
- class simpeg.electromagnetics.time_domain.sources.RampOffWaveform(off_time=0.0, **kwargs)[source]#
Bases:
BaseWaveform
A waveform with a linear ramp-off.
- Parameters:
- off_time
float
, default: 0.0 time at which the transmitter is turned off in units of seconds
- off_time
Attributes
Window of time within which the waveform is considered on
Whether the waveform has initial fields.
Off-time
time_nodes
Methods
eval
(time)Evaluate current waveform at a given time
eval_deriv
(time)Evaluate the time derivative of the linear ramp-off waveform at given times
Examples
>>> import matplotlib.pyplot as plt >>> import numpy as np >>> from simpeg.electromagnetics import time_domain as tdem
>>> times = np.linspace(0, 1e-4, 1000) >>> waveform = tdem.sources.RampOffWaveform(off_time=1e-5) >>> plt.plot(times, [waveform.eval(t) for t in times]) >>> plt.show()
