that looks like a standing wave. As the circuit board makes contact with this wave, the components become soldered to the board. Wave soldering is used...

added to the incoming waves creates a standing wave. An impedance mismatch can be also quantified with the standing wave ratio (SWR or VSWR for voltage), which...

circular fashion to form a ring. The former type is a standing wave cavity, and the latter is a traveling wave cavity. The name microcavity stems from the fact...

Standing waves can be caused by a wave being reflected back through the transmission medium in which it arrived. If the incident and reflected waves are...

particular relevance to stubs. Reflections cause standing waves to be set up on the line. Conversely, standing waves are an indication that reflections are present...
