APPARATUS AND A METHOD FOR GENERATING AN ELECTROMAGNETIC WAVE, CAPABLE OF OSCILLATING THE ELECTROMAGNETIC WAVE OF A HIGH FREQUENCY BY USING A PLURALITY OF ELECTRON BEAMS WITHOUT AN EXTERNAL ELECTROMAGNETIC WAVE SOURCE

摘要

PURPOSE: An apparatus and a method for generating an electromagnetic wave are provided to modulate the remaining electron beam by generating the electron beam inside a first resonator using the part of electron beams.;CONSTITUTION: A first electron beam generation unit(110) generates an electron beam. Second and third electron beam generation units(120,130) are arranged around the first electron beam generation unit and generate the electronic beam. The electronic beams emitted from the first to third electron beam generation units pass through a first resonator(200) with a grid. A plurality of repellers(320,330) is arranged to return the electron beam passing through the first resonator. A second resonator(400) is formed on a progressing path of the electron beam emitted from the first electron beam generation unit. A collector collects the electron beams passing through the second resonator.;COPYRIGHT KIPO 2010
