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.
