Power Monitor Miter Bends
Our power monitors are bi-directional, allowing simultaneous measurement of power traveling in each direction in the high-power waveguide. They use an array of cutoff coupling holes in the mirror. With detectors in fundamental rectangular waveguides, they have inherently fast response. For slower responding but potentially more accurate monitors, see Calorimetric Miter Bends.
In addition, we are developing a power monitor to couple out a complete image of the field in the high-power waveguide. The mirror in that power monitor has coupling holes across the entire surface. The coupled field can be used to monitor and optimize the alignment of the microwave beam from the matching optics unit into the corrugated waveguide.
