The second was a traveling wave applicator with a stub tuner mounted between the adapter and the waveguide, as shown in Fig.
The ripples in the input power were related to the adjustments of the stub tuner to bring the cavity back into a tuned condition.
Here, the reflected power was adjusted to zero at the onset of the experiment by using the stub tuner.
The reduction of the high reflectance of graphite/epoxy laminates by using the stub tuner caused a high electric field strength to build up inside the laminates.
The quarter wave stub tuner devices are three port coaxial connectors with the third port extending from the main through path.
Offering the best-in-class solutions, M/A-COM has developed two different types of protective devices: surge protectors and quarter wave stub tuners.
Providing greater protection for sensitive electronic equipment, quarter wave stub tuners are designed to eliminate concerns about sparkover voltage and residual voltage.
