geoana.em.fdem.HarmonicPlaneWave

class geoana.em.fdem.HarmonicPlaneWave(amplitude=1.0, orientation='X', **kwargs)

Class for simulating the fields and densities for a harmonic planewave in a wholespace. The direction of propogation is assumed to be vertically downwards.

Parameters:

amplitudefloat

amplitude of primary electric field. Default is 1A.

orientation(3) array_like or {‘X’,’Y’}

Orientation of the planewave. Can be defined using as an array_like of length 3, with z = 0 or by using one of {‘X’,’Y’} to define a planewave along the x or y direction. Default is ‘X’.

Attributes
