A passively damped mechanical system is disclosed, for example for use in aerospace applications where vibration can adversely affect navigational and operational instruments. In one example, the passively damped mechanical system includes an end fitting of a strut used to connect a structural element to a payload. The end fitting may include outer and inner cylindrical hubs, with a space between the outer and inner cylindrical hub at least partially filled with a viscoelastic material. In a further example, the passively damped mechanical system includes legs used to connect a structural element to a bracket configured to support a payload. Each leg may include a hollow interior having a lattice structure to add strength and a viscoelastic material to provide passive damping.

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.
