class geoana.em.tdem.VerticalMagneticDipoleHalfSpace(time, **kwargs)#

Transient of a vertical magnetic dipole in a half space.

Only valid for source and receivers at the surface. The surface is assumed to be at z=0.

Waveform is assumed to be the step off.

Attributes

 diffusion_distance Compute diffusion distance for a plane wave in a homogeneous electromagnetic media. epsilon Dielectric permittivity in F/m location Location of the dipole moment Amplitude of the dipole moment of the magnetic dipole ($$A/m^2$$) mu Magnetic permeability in H/m orientation Orientation of the dipole as a normalized vector sigma Electrical conductivity in S/m theta Analog to wavenumber in the frequency domain. time Time (s) used for all computations

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 due to a magnetic dipole over a half space Magnetic flux time derivative due to a step off magnetic dipole over a half space Magnetic flux due to a step off magnetic dipole over a half space Magnetic flux due to a step off magnetic dipole over a half space Compute peak time for a plane wave in a homogeneous electromagnetic media. Vector distance to a set of gridded xyz locations.
