simpeg.electromagnetics.frequency_domain.receivers.PointMagneticField#
- class simpeg.electromagnetics.frequency_domain.receivers.PointMagneticField(locations, orientation='x', component='real', **kwargs)[source]#
Bases:
BaseRx
Measure FDEM total magnetic field at a point.
- Parameters:
- locations(
n_loc
,n_dim
)numpy.ndarray
Receiver locations.
- orientation{‘x’, ‘y’, ‘z’}
Receiver orientation.
- component{‘real’, ‘imag’, ‘both’, ‘complex’}
Component of the receiver; i.e. ‘real’ or ‘imag’. The options ‘both’ and ‘complex’ are only available for the 1D layered simulations.
- data_type{‘field’, ‘ppm’}
Data type observed by the receiver, either field, or ppm secondary of the total field.
- use_source_receiver_offsetbool,
optional
Whether to interpret the receiver locations as defining the source and receiver offset.
- locations(
Attributes
Data component; i.e. real or imaginary.
The type of data for this receiver.
Receiver locations
Number of data associated with the receiver
Orientation of the receiver.
Universal unique identifier
Use source-receiver offset.
Methods
eval
(src, mesh, f)Project fields from the mesh to the receiver(s).
evalDeriv
(src, mesh, f[, du_dm_v, v, adjoint])Derivative of the projected fields with respect to the model, times a vector.
getP
(mesh, projected_grid)Get projection matrix from mesh to receivers
Notes
data_type, use_source_receiver_offset, and the options of ‘both’ and ‘complex’ for component are only implemented for the Simulation1DLayered.
