    • Disclosed herein is an arrangement for shielding individual electronic units from undesired microwave or millimeter wave radiation while providing a means of transferring input and output signals and operating power through the shield wall. A metal box encapsulates an electronic unit. Input and output signals are fed into and transferred from the electronics unit through the shield wall using optical links and photo transmitting and receiving components. Power is transferred through the shield box wall using piezo crystals secured to the outside and inside of the shield box wall and a dielectric rod connected between the two piezo crystals through a hole in the wall. Electrical energy therefore can be transferred into mechanical energy transferred through the box wall to the piezo crystal within where it is received and transferred back into electrical energy. Accordingly, metal feedthroughs are not needed, eliminating any paths for radiation to enter the shield box.
    • 本文公开了一种用于屏蔽各个电子单元免受不期望的微波或毫米波辐射的设置,同时提供传输输入和输出信号以及通过屏蔽壁工作电力的装置。 金属盒封装电子单元。 输入和输出信号通过光纤链路和照片发送和接收组件通过屏蔽墙馈送到电子单元并从电子单元传输。 电力通过屏蔽箱壁传递,使用固定在屏蔽箱壁的外部和内部的压电晶体,以及通过壁中的孔连接在两个压电晶体之间的介电棒。 因此,电能可以转移到通过箱壁传递到机械能的压电晶体中,在其中它被接收并转移回电能。 因此,不需要金属馈通,消除了辐射进入屏蔽盒的任何路径。
