John: We study the 2nd picture. There're 2 types of loss. One is insertion loss. And, one is reflection loss.
Me: OK.
.
John: Insertion loss is a real loss.
Me: Why is it real loss?
John: Because, part of the power of the signal enter the ground before they enter the inductor. In another words, part of the power of this signal is attenuated.
Me: OK.
John: Therefore, the "power" of the signal isn't completely assigned to terminal B.
Me: OK.
John: However, is "reflection loss" a real loss?
Me: Not really.
John: Why not?
Me: Because, the power of the signal completely pass through the inductor. It is only that when the signal is being affected at terminal B, there is a reflection.
John: Such reflection isn't a real loss.
