Geometric coefficient for the lateral device

Input(s)

AM: Midpoint Between Electrodes a and $\mathrm{M}(\mathrm{m})$

$A N$: Midpoint Between Electrodes a and $\mathrm{N}(\mathrm{m})$

$M N$: Midpoint Between Electrodes $\mathrm{M}$ and $\mathrm{N}(\mathrm{m})$

Output(s)

$G_{L}$: Geometric Coefficient for the Lateral Device (m)

Formula(s)

$$ G_{L}=4 * \pi *\left((A M) * \frac{A N}{M N}\right) $$
