The measurement of current at radio frequencies

The state-of-the-art of radio-frequency current measurement is reviewed with emphasis on the most useful standards. In particular, thermocouple and electrodynamic ammeters are discussed in detail. Reference is made to photoammeters, air thermometer milliammeters, and other types of current-measuring apparatus, some of which deserve additional development. Extensive referencing is included for the convenience of investigators interested in an intensive review of radio-frequency current measurements.
