VSWR = voltage standing wave ratio = ratio of the maximum voltage to minimum on a line
= VSWR = Emax / Emin = Imax / Imin
Reflection Coefficient is the ratio of reflected voltage to incident voltage. = ZL - ZO / ZL + ZO

3M uses RA as the symbol for the coefficient of retroreflection.
-- frequency -- power -- VSWR -- current -- voltage -- resistance -- impedance -- inductance -- capacitance -- power factor -- air pressure -- sound power level -- received signal level -- distance to fault -- return loss -- water pressure -- reflection coefficient -- temperature -- light intensity -- RF field strength -- speed -- altitude -- flow rate -- wind speed -- noise power ratio -- baseband intrinsic noise ratio -- fuel level -- oil presssure -- magnetic field strength -- transmission coefficient (transparency) -- engine speed RPM -- acceleration
coefficient
2X 2 is the coefficient
The coefficient is the number that multiplies a value. For example, the coefficient of 4x is 4. If n+3 is in brackets in the form (n+3) then the coefficient is one. If not the the coefficient of n is also 1.
