"Let`s look at the following system with two sources," Is this tempest about creation of an oppositely phased wave to cancel a reflection? A way to avoid reflected waves within a waveguide is mentioned by Terman on page 148 of his 1955 edition: "Create a reflected wave near the load that is equal in magnitude but opposite in phase from the wave reflected by the load; in this way the two reflected waves cancel each other." "Some of these (matching arrangements) are analogous to the impedance matching arrangements employed in transmission lines (described in Sec. 4-11) while others are unique to waveguides."
