geoana.em.static.ElectrostaticSphere

class geoana.em.static.ElectrostaticSphere(radius, sigma_sphere, sigma_background, primary_field=None, location=None)

Class for electrostatic solutions for a sphere in a wholespace.

The ElectrostaticSphere class is used to analytically compute the electric potentials, fields, currents and charge densities for a sphere in a wholespace.

Parameters:

radiusfloat

radius of sphere (m).

sigma_spherefloat

conductivity of target sphere (S/m).

sigma_backgroundfloat

background conductivity (S/m).

primary_field(3) array_like, optional

amplitude of primary electric field. Default is (1, 0, 0).

location(3) array_like, optional

center of the sphere. Default is (0, 0, 0).

Attributes

location	Center of the sphere.
primary_field	Amplitude of the primary current density.
radius	Radius of the sphere in meters.
sigma_background	Electrical conductivity of the background in S/m.
sigma_sphere	Electrical conductivity of the sphere in S/m.
