<p>Apparatus for measuring the power of intense microwave pulses comprises a calorimeter (2) and frequency selective band limiting means (3). Heating of liquid contained within the calorimeter (2) when irradiated, expands in a capillary (5) thus indicating the amount of energy emitted by a microwave source (1). The band limiting means comprises a dielectric substrate on which an array of electrically-conductive elements are printed. The invention has the advantage of allowing repeated measurements of energy emitted by a pulsed source (1) within a particular frequency band. Furthermore, it requires no triggering means.</p> |
