| 摘要 |
An electromagnetic wave energy emitter including a generally cylindrical probe including generally coaxial first and second electrodes, each of the electrodes having an at least partially cylindrical shape, one of the electrodes being energizable to emit electrons and the other of the electrodes being adapted to receive the electrons and generate electromagnetic wave energy. A grid element may be placed between the first and second electrodes. A controller may be in communication with the grid element, adapted to control a potential of the grid element. The grid element may have an at least partially cylindrical shape. The grid element may be placed concentrically or non-concentrically with respect to the first and second electrodes. |
