In an embodiment, a radar or other system emitting electromagnetic energy is disposed with an optical system or other imaging system in a common housing. A shielding device or shroud protects the optical or other imaging system from the electromagnetic energy emitted from the radar system. The shielding device captures and dissipates electromagnetic signals reflected from a radome in accordance with structural geometry of the shielding device that may be covered with a radiation-absorbent material (RAM) or coating. The shielding device geometry includes angular faces configured to dissipate the electromagnetic signals.
