Abstract: A method of electromagnetically shielding a sensor window with a metallization coating including providing a randomized elliptical grid pattern having a plurality of randomly distributed elliptical shapes, where providing includes arranging the elliptical shapes on the sensor window such that the elliptical shapes are physically connected to each-other as a result of direct shape-to-shape contact or overlap, where arranging includes increasing a pattern density, which is a ratio of elliptical shapes per unit of sensor window area, towards an edge of the sensor window; and where the elliptical shapes are hollow to allow for transmission of electro-optical radiation through the sensor window.

Abstract: A randomized elliptical grid disposed on a sensor window for electro-magnetic and/or radio-frequency shielding of sensors, and a method of applying same. Grids may be made of electrically conductive or resistive material and may include elliptical or circular shapes. The shapes are in physical contact with each-other and preferably do not contain straight lines to reduce detection artifacts caused by the coating. Grid element shape, size, orientation, and grid pattern density may be randomized or varied across a sensor window.
