This appendix includes the calculations of the probability density functions and the moments of the total field and power variables. By total variables, we mean the fields or the powers measured by probes or antennas, which simultaneously collects the three *E _{x}*,

The total field variable taking *E _{t}* as a notation is given by the square root of the sum of six terms made up of all the square complex components of each

[A3.1]

The normalized variable of the total field is designated for the occasion by the lower case *e _{t}* notation. This variable comes from the extension of the definition introduced in section 3.2.3:

We find in this formula the standard deviation *σ _{ν}*, which is attached to the complex components of

Knowing that the *E _{x} _{y} _{z}* variables all follow the normal probability distribution,the square amplitude of the normalized total

[A3.3]

We can thus add to this variable, the pdf of *χ*^{2}, which is expressed by the notation conventions of ...
