the specular patterns of conductive paths may be applied to a structure and used as a stealth agent to cloak the structure from enemy radar i e render it substantially transparent to radar for example a chosen pattern of conductive paths may be integrated into composite material forming a skin of the structure like an airfoil of an aircraft for example with the addition of the pattern of conductive paths the structure becomes a radar altering structure ras so that the radar cross sectional area of the structure is substantially reduced it is further understood that the same pattern of conductive paths need not be applied to the overall structure for example it may be desired that one pattern be applied to the top of an airfoil and a different pattern be applied to the bottom thereof or one pattern may be applied to the front surface of the airfoil while a different pattern may be applied to the rear surface thereof different specular patterns may be even applied in a plurality of layers to the structure accordingly to render the structure a radar altering structure may involve applying one or more patterns of conductive paths to respective portions of the structure and electrifying the conductive paths thereof in addition once applied to the structure the pattern of conductive paths may be controlled to create special radar signatures of the structure to illuminating radars for example the conductive paths 16 of the pattern 10 may be coupled to a ras switch system 30 as shown in the schematic illustration of fig9 and operated as a special antenna to illuminating radars referring to fig9 the system 30 may be operative to connect and disconnect the.
