Abstract
IN an earlier note1, a method of measuring microwave power by radiation pressure was described. Some experimental results have now been obtained. The power to be measured was fed through an uncompensated wave-guide T-junction to a matched water-load forming part of a balanced calorimeter power-measuring apparatus of the type described by L. B. Turner2. This provides a reliable independent measurement of the power.
