OPEN-CIRCUITED COAXIAL LINES AS STANDARDS FOR MICROWAVE MEASUREMENTS.

A highly accurate electromagnetic characterization of open-circuited coaxial lines terminating in a circular waveguide has been obtained with a view to the employment of such devices as calibration standards for microwave measurements. The theoretical results have been compared with the corresponding experimental data in the range from 1 kHz to approximately 18 GHz for an open-line standard for common use. The agreement is good.
