Abstract
Possible methods of microwave power measurement are reviewed. The design requirements for bolometric wattmeters are outlined, and examples are given of bolometer elements that have been developed to meet these requirements. A recently developed bolometer element that may be used over an exceedingly wide band of frequencies is included. The results of experiments to investigate sources of error and to determine the accuracy of these wattmeters are summarized. These experiments indicate that, although serious errors are possible, proper usage will hold errors to within a few per cent.Keywords
