please explain somebody what it means I am totally confused.
When we can say that a waveguide is perfectly matched?

SUMMARY
A waveguide is considered perfectly matched when there is no reflected power at its termination interface. This principle applies to all transmission lines, including RF transmission lines and coaxial cables. Achieving a perfect match is practically impossible; therefore, circulators are employed to redirect reflected power into a dummy load, preventing interference and undesirable intermodulation products in the transmitter. Understanding this concept is crucial for effective RF system design.

Hi there
welcome to PF
its perfectly matched where there is no reflected power from the interface of whatever the waveguide is terminating into
this goes for any transmission line
of course a perfect match would be near impossible to obtain and we would always have to put up with some reflected signal
which is why in RF transmission lines, coax or waveguides, we use circulators to terminate reflected power into a dummy load, rather than letting it go back into the transmitter where it will produce all sorts of nasty intermodulation products
if you need a better explanation than that, then maybe ask a more specific question
cheers
