Convert scattering parameters with the reference impedance 'zref' to scattering parameters with the reference impedance 'z0'.

Detail are given in [1], under equation (32)

New scatering matrix $S'$ is:

$S'=A^{-1}(S-\Gamma^+)(I-\Gamma S)^{-1}A^+$

Where x^+ is the adjoint (or complex tranposate) of x, I the identity matrix and $A$ is diagonal the matrix such as: $\Gamma_i= r_i$ and $A$ the diagonal matrix such as:

$A_i = \frac{(1-r_i^*)\sqrt{|1-r_ir_i^*|}}{|1-r_i|}$

Where $x*$ is the complex conjugate of $x$ and $r_i$ is wave reflexion coefficient of $Z_i'$ with respect to $Z_i^*$ (where $Z_i'$ is the new impedance and $Z_i$ is the old impedance), ie:

$r_i = \frac{Z_i'-Z_i}{Z_i'-Z_i^*}$

Parameters:

Scattering parameters to admittance matrix.

Convert scattering parameters to admittance matrix. According to [1] eq (19):

$Z=F^{-1} (I- S)^{-1} (SG + G^+) F$

Where $S$ is the scattering matrix, $x^+$ is the adjoint of x, I the identity matrix. The matrix F and G are diagonal matrix defined by:

$\begin{align*} F_i&=\frac{1}{2\sqrt{\Re\text{e}\; Z_i}} \\ G_i&=Z_i \end{align*}$

Using the well know formula $(AB)^{-1}=B^{1}A^{1}$ , we derivate:

$Y=F^{-1} (SG+G^+)^{-1} (I-S) F$

Parameters:

[in]	s	Scattering matrix
[in]	z0	Normalisation impedance

Note:: We could safely drop the in because we compute $FXF^{-1}$ and therefore will simplify.

Scattering parameters to impedance matrix.

Convert scattering parameters to impedance matrix. According to [1] eq (19):

$Z=F^{-1} (I- S)^{-1} (SG + G^+) F$

Where $S$ is the scattering matrix, $x^+$ is the adjoint of x, I the identity matrix. The matrix F and G are diagonal matrix defined by:

$\begin{align*} F_i&=\frac{1}{2\sqrt{\Re\text{e}\; Z_i}} \\ G_i&=Z_i \end{align*}$

Parameters:

[in]	s	Scattering matrix
[in]	z0	Normalisation impedance

Note:: We could safely drop the in because we compute $FXF^{-1}$ and therefore will simplify.

Bug:: not correct if zref is complex

Todo:: s, z0 const

Returns:: Impedance matrix

Admittance matrix to scattering parameters.

Convert admittance matrix to scattering parameters. Using the same methodology as [1] eq (16-19), but writing (16) as $i=Yv$ , ie

$S=F(I-G^+Y)(I-GY)^{-1}F^{-1}$

Where $S$ is the scattering matrix, $x^+$ is the adjoint of x, I the identity matrix. The matrix F and G are diagonal matrix defined by:

$\begin{align*} F_i&=\frac{1}{2\sqrt{\Re\text{e}\; Z_i}} \\ G_i&=Z_i \end{align*}$

$Y=F^{-1} (SG+G^+)^{-1} (I-S) F$

Parameters:

[in]	y	admittance matrix
[in]	z0	Normalisation impedance

Note:: We could safely drop the in because we compute $FXF^{-1}$ and therefore will simplify.
