    Open Circuit Termination for Waveguides in High Frequency Labs

    Hi everyone, I am trying to understand that why do we use open circuit terminator for wave guides or any RF element such as coupler and etc. I know if we just leave it open, it does not work as open circuit. But why?

    I don't know what is a cutoff stub. For double stub matching you can check the book Microwave Engineering by David Pozar.

    I'm sorry about the pics. Here, i hope it is better

    Impedance matching and Smith diagram.

    I try to solve for d=0.1λ. If it is correct you can follow same procedure. Firts, if there is a match, impedance of point A should be 1. Now, we can find impedance of point B(please check attachments). ZB=ZA-Z2=1-1.2j Now, show this impedance on the chart. Wave length of this point is...

    If you don't have a hurry i can take look.
