A magnetic-controlled detection system, with a rectangular solenoid coil in a waveguide test fixture, is proposed for radar absorbing coatings. By applying Ku-band rectangular waveguide, the field patterns at different positions, the reflection coefficient S11 and its variation of several coating samples are simulated and measured under current loaded from 0 to 1.0 A. The results show that this detection system is repeatable and stable, and also reliable with the error of less than 10%.

Reflection Probe

A microwave reflection probe method allowing the local measurement of electron densities well above the critical density is described. Measurements in the 35 Gc/s band on a z-pinch show its applicability. A rectangular waveguide with a dielectric aperture window serves as a probe. The interferometer for measuring the reflection coefficient is presented. It indicates phase angle and amplitude automatically without using modulators or frequency translators. Electron densities between about 1013 cm-3 and 1016 cm-3 could be measured, facilitated by the transforming action of a dielectric λ/4-window.
