get_receiver_response¶

emg3d.fields.get_receiver_response(grid, field, rec)[source]¶

Return the field (response) at receiver coordinates.

Note that in order to avoid boundary effects the first and last value in each direction is neglected. Field values for coordinates outside of the grid are set to NaN’s.

Parameters:

grid : emg3d.meshes.TensorMesh

The model grid.

field : Field

The electric or magnetic field.

rec : tuple (x, y, z, azimuth, dip)

Receiver coordinates and angles (m, °).

All values can either be a scalar or having the same length as number of receivers.

Angles:

azimuth (°): horizontal deviation from x-axis, anti-clockwise.
dip (°): vertical deviation from xy-plane up-wards.

Returns:

responses : utils.EMArray: Responses at receiver.

Note

Currently only implemented for point receivers, not for finite length dipoles.
