Wading through file I have not been able to find what variables "Linear" and "SWR Linear" mean.
Looking at formulas on the spreadsheet, "Linear" ( Column G) contains the absolute value (magnitude) of S11, IS11I, which is in polar terms the magnitude "rho", as used in the polar notation for Gamma (or reflection coefficient) Gamma= rho * Angle Theta. One might replace "Linear" with "Rho".
"Rho" is used to calculate "Return Loss," being defined as RL= 20log(1/rho)
Rho is also used in the VSWR calculation: VSWR = (!+ Rho)/(1-Rho)
As far as SWR:Linear is concerned (column H), the formula indicates it is the the SWR Value (column F) divided by 10 x "linear" or "rho".
I've never seen that description (SWR:Linear) in practice or use, but a new dawn rises daily.
Can anyone shed light on what this ration SWR:Linear might be used for?
