simpeg.electromagnetics.frequency_domain.receivers.PointMagneticField#

class simpeg.electromagnetics.frequency_domain.receivers.PointMagneticField(locations, orientation='x', component='real', **kwargs)[source]#

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.

Notes

data_type, use_source_receiver_offset, and the options of ‘both’ and ‘complex’ for component are only implemented for the Simulation1DLayered.

Attributes

`component`	Data component; i.e. real or imaginary.
`data_type`	The type of data for this receiver.
`locations`	Receiver locations
`nD`	Number of data associated with the receiver
`orientation`	Orientation of the receiver.
`uid`	Universal unique identifier
`use_source_receiver_offset`	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
