empymod models the EM Green's function for electric and magnetic sources and receivers, and can, as such, model any EM method and any survey layout. However, the implementation can sometimes be tricky. It would therefore be good to add some easy high-level routines to model some of them, e.g. TEM.

One such feature that is possible, but could be made much easier, is arbitrary waveforms. Currently the high-level time-domain routines only contain impulse and step-on and -off functions. However, it is not too difficult to allow any arbitrary waveform.

Alternatively, if not implemented properly, than we should at least provide some detailed examples.
