Hi.

In *.out files, for a gain pattern, we can see the following sequences: 

        LOCATION          ETHETA             EPHI                 gain in dB                 POLARISATION    THETA    PHI      magn.    phase     magn.    phase     vert.     horiz.    total     axial r. angle   direction  -180.00    0.00   1.510E-14  -63.33  1.310E-14  119.93  -267.4753 -268.7116 -265.0393   0.0282   -40.93   RIGHT   -172.50    0.00   1.187E-01  174.09  0.000E+00    0.00    -9.5712 -999.9999   -9.5712   0.0000   180.00   LINEAR  -165.00    0.00   2.144E-01  175.75  0.000E+00    0.00    -4.4304 -999.9999   -4.4304   0.0000   180.00   LINEAR  -157.50    0.00   2.715E-01  178.76  0.000E+00    0.00    -2.3802 -999.9999   -2.3802   0.0000   180.00   LINEAR  -150.00    0.00   2.851E-01 -176.41  0.000E+00    0.00    -1.9559 -999.9999   -1.9559   0.0000   180.00   LINEAR  -142.50    0.00   2.614E-01 -168.79  0.000E+00    0.00    -2.7093 -999.9999   -2.7093   0.0000   180.00   LINEAR  -135.00    0.00   2.149E-01 -156.43  0.000E+00    0.00    -4.4114 -999.9999   -4.4114   0.0000   180.00   LINEAR  -127.50    0.00   1.660E-01 -135.53  0.000E+00    0.00    -6.6560 -999.9999   -6.6560   0.0000   180.00   LINEAR  -120.00    0.00   1.405E-01 -103.19  0.000E+00    0.00    -8.1039 -999.9999   -8.1039   0.0000     0.00   LINEAR

How the POSTFEKO gets total gain in these points and show them to user?

What is the calculation behind that?

Thanks...

    Hi mustaphos

     

    This information is contained in Section 20-6 of the FEKO User Manual. This can be found by clicking 'FEKO Help' under the Help menu in CADFEKO or (as a PDF document - UserManual.pdf) located in the doc folder of your FEKO installation.

     

    Specifically the total gain is given by Equation 20-14.

     

    Regards,

    Johan H
