- class SimPEG.electromagnetics.time_domain.sources.HalfSineWaveform(ramp_on, ramp_off, **kwargs)#
A waveform that has a quarter-sine ramp-on and a quarter-cosine ramp-off.
When the end of ramp-on and start of ramp off are on the same spot, it looks like a half sine wave.
- ramp_on: tuple
times during which there is a quarter-sine ramp-on
- ramp_off: tuple
times between which there is a quarter-cosine ramp-off.
Evaluate current waveform at a given time
Evaluate the time derivative of the linear ramp-off waveform at given times
