property Dipole.geometric_factor#

Calculate geometric factor for every receiver.

Consider you have current electrodes A and B, and potential electrodes M and N. Let $R_{AM}$ represents the scalar horizontal distance between electrodes A and M; likewise for $R_{BM}$, $R_{AN}$ and $R_{BN}$. The geometric factor is given by:

$$G=\frac{1}{C}[\frac{1}{R_{AM}}-\frac{1}{R_{BM}}-\frac{1}{R_{AN}}+\frac{1}{R_{BN}}]$$

where $C=2\pi$ for a halfspace and $C=4\pi$ for a wholespace.

Returns:

(nD) numpy.ndarray

Geometric factor for each datum
