1. A metallization coating for a sensor window, the coating comprising:
- a randomized elliptical grid pattern, the pattern including a plurality of randomly distributed elliptical shapes arranged such that the elliptical shapes disposed on the sensor window are physically connected to each-other as a result of direct shape-to-shape contact or overlap; 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.
