class SimPEG.electromagnetics.frequency_domain.sources.PrimSecMappedSigma(receiver_list=None, frequency=None, primarySimulation=None, primarySurvey=None, map2meshSecondary=None, **kwargs)[source]#

Bases: BaseFDEMSrc

Primary-Secondary Source in which a mapping is provided to put the current model onto the primary mesh. This is solved on every model update. There are a lot of layers to the derivatives here!

Parameters:
receiver_listlist of SimPEG.electromagnetics.frequency_domain.receiver.BaseRx

List of FDEM receivers

frequencyfloat

Frequency

primarySimulationBaseFDEMSimulation

Base simulation

primarySurveyBaseEMSimulation

Primary FDEM survey

map2meshSecondarymaps.BaseMap

Mapping current model to act as primary model on the secondary mesh

Methods

bPrimary(simulation[, f])

Compute primary magnetic flux density

ePrimary(simulation[, f])

Compute primary electric field

ePrimaryDeriv(simulation, v[, adjoint, f])

Compute derivative of primary electric field times a vector

s_e(simulation[, f])

Electric source term (s_m)

s_eDeriv(simulation, v[, adjoint])

Derivative of electric source term with respect to the inversion model
