Abstract :
We present a new high-performance small-sized multi-beam device, called a rezotrod, for uniform volumetric heating of large-sized objects. It has the advantages of UHF devices (complete passage of a current, closed electrodynamics systems), and grid tubes (supply without modulation, small length electrostatic focusing). It also has its own distinctive advantages (stabilized amplitude of an UHF voltage in an output gap, independent generating contour)
