Analyzing a device under test ('DUT') at higher frequencies. A phase shifter varies the phase of a standing wave on a transmission line coupled to the DUT. The standing wave magnitude is sampled at each of the phase shifts and one or more DUT characteristics are determined as a function of the sampled magnitudes and phase shifts. Further aspects include a related phase shifter comprising a waveguide having a plurality of sub-resonant slots formed therein and having active elements for loading the slots to control the phase shift applied to the signal.

High frequency analysis of a device under test

A sensor array having a plurality of modulated slots for microwave and/or millimeter wave imaging. The locations of the slots in the array define a spatial domain away from an object for detecting an electric field from the object. Each of the slots outputs a signal representative of the measured field and the location of the slot. A processor decodes the signals and generates an image of the object.
