ABSTRACT:
A compact tunable generator of radio frequency (RF) electromagnetic energy is disclosed. A thin conducting film is applied to a diffraction grating formed from a nonconducting substrate. A voltage source is applied to the film so that a current flows in the convoluted plane of the film in a direction perpendicular to the grooves of the grating. The frequency of the RF energy radiated by this system is determined both by the grating spacing and the applied voltage. The power levels are adequate for testing sensitive receiver systems over a wide range of frequencies.
