Output files

show the output file

The output file contains information about the computation (input information, generated files, computation time, gain, S parameters, ...).

The totalResults.txt file contains all the results, except the frequency range (only the last frequency is stored in that file). The results.txt file is generated during the post-processing. It takes into account the parameters of the Results Visualisation (frequency, selected geometry parts, contributions).

If a frequency range is computed, the output far field patterns are stored in spirent format files. The name of these file contains the operating frequency. There is a gain file and a phase file. A right circular polarisation is assumed.

Let us consider the far field pattern. The electric field computed. The 1/r term is omitted. A spherical coordinate system is used to describe the direction of observation :

Coordinate system used to describe the polarisation :

The header contains :

Operating frequency
θmin θmax θstep (degrees)
ϕmin ϕmax ϕstep (degrees)
2 lines of comments

For each direction of observation, there are 12 columns :

1 - 2 : θ and ϕ (degrees)
3 - 4 : amplitude (Volts) and phase (degrees) of the projection of the electric field on the vector eθ, named Etheta
5 - 6 : amplitude (Volts) and phase (degrees) of the projection of the electric field on the vector eϕ, named Ephi
7 : vertical gain (dB), defined as 20 * log10( |Etheta| ), normalized by the maximum gain value
8 : horizontal gain (dB), defined as 20 * log10( |Ephi| ), normalized by the maximum gain value
9 : total gain (dB), defined as 20 * log10( |Etheta|2 + |Ephi|2 ), normalized by the maximum gain value
10 : Emin / Emax ratio (0 for a linear polarisation, 1 for a circular polarisation)
11 : α angle
12 : polarisation (LINEAR, LEFT or RIGHT)
