“Invisibility” is a goal that has been long sought after by the Militaries. An operational cloaking chip could be an extension of technologies such as radar-absorbing dark paint used on stealth aircraft, local optical camouflage, surface cooling to minimize electromagnetic IR emissions, or electromagnetic wave scattering. Metamaterials are the primary materials …

Sonars are one of the primary systems for detection and tracking of submarines in Anti Submarine warfare. However modern nuclear and diesel electric submarines have become very stealthy and quiet. Another challenge is diesel-electric submarines operating in littoral waters which generate high false alarm rates (FAR). One of the ways …
