class geoana.em.fdem.MagneticDipoleHalfSpace(frequency, **kwargs)#

Class for a harmonic magnetic dipole in a wholespace.

Attributes

 epsilon Dielectric permittivity in F/m frequency Frequency (Hz) used for all computations location Location of the dipole moment Amplitude of the dipole moment of the magnetic dipole ($$A/m^2$$) mu Magnetic permeability in H/m omega Angular frequency orientation Orientation of the dipole as a normalized vector sigma Electrical conductivity in S/m sigma_hat Conductivity including electric displacement term. skin_depth Returns the skin depth for an electromagnetic wave in a homogeneous isotropic medium. wavenumber Wavenumber for an electromagnetic planewave in a homogenous isotropic medium.

Methods

 Cross products between a gridded set of vectors and the orientation of the source. distance(xyz) Scalar distance from dipole to a set of gridded xyz locations Dot product between the orientation of the source and a gridded set of vectors. magnetic_field(xy[, field]) Magnetic field due to a magnetic dipole over a half space Vector distance to a set of gridded xyz locations.
