Yyefj reacted to Baluncore's post in the thread Resonance definition through dip in S-parameters with
Like.
The cancellation occurs where the stub joins the line between port 1 and port 2. The forward wave in the stub is reflected from the... -
Yyefj replied to the thread Resonance definition through dip in S-parameters.Hello baluncore , from reading at the following link resonance is a situation when we have standing waves. is this what happens here...
