Abstract (en)
An electron beam device comprises a cold cathode 1, modulation means 2 and an anode 3. The components of the device have a longitudinal configuration and enable an electron beam produced by the cathode 1 to be transversely modulated with a microwave signal transmitted along the modulator waveguide structure 2. The modulated output may be propagated along the elongate anode 3 or may be arranged to propagate through the anode substrate 5 and interface directly with an antenna or other circuit element. <IMAGE>
