Image Loop Probe for Measurement of Microwave Surface Currents

摘要

A shielded, image loop probe suited to precision measurements of surface current distributions at microwave frequencies has been constructed. Its design permits continuous rotation of the probe element so that the vector direction of the current flow may be determined. Tests evaluating the probe errors indicate good accuracy can be achieved in measurements of the phase, amplitude, and direction of a surface current at 10,000 megacycles per second. (Author)
