Abstract: An FED, modified with an electrostatically deformable anode, has a control network attached to electrodes thereof to switch the FED off as the anode is deformed by electrostatic force and switch the FED on as the anode returns to a quiescent state. Frequency selectivity is realized by incorporating a variable frequency determining network within the control network.
Abstract translation: 用静电可变形阳极修改的FED具有连接到其电极上的控制网络,以在阳极由静电力变形时关闭FED,并且当阳极返回到静止状态时将FED切换。 频率选择性通过在控制网络内并入可变频率确定网络来实现。
