ABSTRACT:
A method and apparatus for generating microwave radiation includes a cathode, comprising parallel side wall means, a first end wall and a second end wall parallel to the first end wall, which defines a space. An aperture is defined within each of the end walls. An elongated anode extends across the defined space and outwardly through the apertures. Free electrons are generated adjacent to the anode and a positive potential is applied between the cathode and the anode. Electrons are trapped in a surrounding relation with the anode and microwave radiation is generated. In an alternate embodiment, a pair of spaced-apart radial steps in the radius of the anode is used to replace the first and second end walls to form electrostatic mirrors for confining free electrons therebetween.
