the load impedance must be the complex conjugate of the source impedance so Z2=R-jX
Not sure that's true, but I have to admit, that's the part of SWR theory that I struggle the most
If you check formula for reflection coefficient ( R = (Z1-Z2)/(Z1+Z2) ) and any random "online calculator, all of them line up with Z1 = Z2, and not the conjugate
Conjugate assures max transfer of power as reactance's null each other (kind of a "system's resonance" of some kind). But then, expectation is that the max power transfer happens for SWR 1:1. The reason we don't see that "questioned" more often is because we all start with assumption that Z1=50, so conjugate becomes irrelevant concept :)
Hope someone here can clear that up :)
