    • The invention includes a dust mitigation device that utilizes electromagnetic waves to protect devices from dust deposition. The device includes a nonconducting (dielectric) material separating at least one electrode, and in some embodiments a plurality of electrodes, from a grounded layer. The electrodes are connected to a single phase AC signal or a transient voltage signal. In some embodiments the grounded layer is created using a continuous conductor or a conductive grid. In some embodiments, the dielectric, the electrodes, and/or the grounded layer are transparent. The electromagnetic fields produced by the electrodes lift dust particles away from the shield and repel charged particles. Deposited dust particles are removed from the dust mitigation device when the electrodes are activated, regardless of the resistivity of the dust. The invention further includes a method of mitigating dust using such components.
    • 本发明包括利用电磁波来保护装置免受灰尘沉积的灰尘减轻装置。 该器件包括从接地层分离至少一个电极,并且在一些实施例中分离多个电极的不导电(电介质)材料。 电极连接到单相交流信号或瞬态电压信号。 在一些实施例中,使用连续导体或导电栅格产生接地层。 在一些实施例中,电介质,电极和/或接地层是透明的。 由电极产生的电磁场将灰尘颗粒从屏蔽件上排出并排斥带电粒子。 无论灰尘的电阻率如何,当电极被激活时,沉积的灰尘颗粒从灰尘缓解装置中移除。 本发明还包括使用这些部件减轻粉尘的方法。
