Return electromagnetic frequency-domain response.

This function is called from one of the modelling routines empymod.model. Consult those for more details regarding the input and output parameters.

This function can be used directly if you are sure the provided input is in the correct format. This is useful for inversion routines and similar, as it can speed-up the calculation by omitting input-checks.
