void rectline::calcPropagation ( nr_double_t  frequency)
private

Compute propagation constant

According to [1] table 3.2 p 128 Wawe number in vacuum is:

\[ k=\omega\sqrt{\mu\varepsilon}=\omega\sqrt{\mu_r \varepsilon_r \mu_0 \varepsilon_0} \]

Where $\omega=2\pi f$, $f$ is the frequency, $$ the magnetic permeability, $\varepsilon_r$ the permitivity. Using well known formula $c^2\mu_0\varepsilon_0=1$, we found:

\[ k=\frac{\omega}{c} std::sqrt{\mu_r \varepsilon_r} \]

In general case $k_c$ is:

\[ k_c = \sqrt{\left(\frac{m\pi}{a}\right)^2+\left(\frac{n\pi}{b}\right)^2} \]

Where $a$ is the wider dimension of the guide and $b$ the smaller and $(n,m)\in\mathbb{N}^2$. In the TE10 case it simplifies to:

\[ k_c = \sqrt{\left(\frac{\pi}{a}\right)^2} = \frac{\pi}{a} \]

The propagation constant is:

\[ \beta = \sqrt{k^2 - k_c^2} \]

Loss could be divised in dielectric and resistive loss. Dielectric loss are computed using:

\[ \alpha_d = \frac{k^2 \tan \delta}{2\beta} \]

Resistive using [1] eq (3.96) p 125 (valid only for TE10 mode)

\[ \alpha_c=\frac{R_s}{a^3 b \beta k Z_0} \left( 2 b \pi^2 + a^3 k^2 \right) \]

Wave impedance is for TE10:

\[ Z = \frac{k Z_0}{\beta} \]
