Abstract
The formula (4) must be replaced by :


\begin{displaymath}\frac{\phi}{2\pi} = \frac{1}{\lambda}\int_{0}^{e}n\cos r dz
- \frac{1}{\lambda}\int_{0}^{e}n'\cos r' dz \; \; \; (4)\end{displaymath}

Where the first integral corresponds to the ray travelling along with the z direction and the second to the ray going in the reverse direction.

In the same way, the formula (12) must be replaced by :


\begin{displaymath}\frac{\phi}{2\pi} = \frac{h}{\lambda}[n\cos r + n'\cos r']
\; \; \; (12)\end{displaymath}

where $n'\cos r'$ is deduced from $n\cos r$ by changing $\theta$ in $-\theta$.

As a result, the term $\displaystyle -k\ln\frac{k^2}{n_e^2}$ in the formula (16) must be disregarded and the 1 in the formula (17) as well.
