$\theta = \arctan\left( T \cdot \pi \cdot D_{out} \right)$

Where :

$\theta$ : pitch angle
: Number of twists per unit length
$D_{out}$ : Wire diameter with insulation

$e_{eff} = e_{env} \cdot \left( 0.25 + 0.0007 \cdot \theta^2 \right)\cdot\left(e_r-e_{env}\right)$

Where :

$e_{env}$ : relative dielectric constant of air ( or some other surronding material ),
: relative dielectric constant of the film insulation,
$e_{eff}$ : effective relative dielectric constant

$Z_0 = \frac{Z_\mathrm{VACUUM}}{\pi \cdot \sqrt{e_{eff}}}\cosh^{-1}\left(\frac{D_{out}}{D_{in}}\right)$
: line impedance
$Z_\mathrm{VACUUM}$ : vacuum impedance
$D_{in}$ : Wire diameter without insulation

◆ minimizeZ0Error1D()

bool TRANSLINE::minimizeZ0Error1D ( double * aVar )

protectedinherited

@function minimizeZ0Error1D

Tries to find a parameter that minimizes the error ( on Z0 ). This function only works with a single parameter. Calls calcAnalyze several times until the error is acceptable. While the error is unnacceptable, changes slightly the parameter.

This function does not change Z0 / Angl_L.
