Note: Smart nanocoatings: The necessity of utilizing nanotechnology in the manufacture and production of smart anti-wave and radar-evading coatings has become more apparent.
One way to make military equipment such as aircraft, ships and submarines invisible to radar is to use smart coatings. Radars work by producing and emitting electromagnetic waves with a transmitter and receiving a possible echo through a receiver. If there is an echo, the radar screen shows it as a bright spot, and radars are also able to detect the distance and speed of the target by calculating the time it takes for the waves to travel and return. Metals reflect radar waves well; therefore, the metal body of an aircraft is an ideal body for reflecting signals emitted by a radar. It is also used to make military targets such as aircraft and ships invisible:
Reshaping the body of military targets: By reshaping the body of military targets, it is possible to direct the reflection of waves emitted from the radar in a direction other than the radar equipment. Most of the existing aircraft have a curved shape.

This type of design, while making them aerodynamic, causes radar waves to be reflected towards the radar equipment when they hit any part of the aircraft, while changing the shape of the structure from a curved shape to surfaces with sharp edges can cause radar waves to spread in directions other than those detectable by the radar.

Applications of absorbent nano-coatings in multiple military industries (non-intercept coating)
Smart nanocoatings, utilizing active nanoparticles and appropriate functional groups in the carrier structure, are able to exhibit intelligent protective, restorative, absorbing, repelling, or neutralizing responses to environmental stimuli. Among the most practical smart nanocoatings in the military, aerospace, and marine industries are smart anti-radar coatings that are capable of early detection and prevention of detection of metal equipment.
Bioactive nanocoatings, such as antibacterial and anti-moss coatings, are also used to prevent damage caused by the accumulation of microorganisms on metal structures and to prevent weight gain in marine equipment, such as submarines and military frigates, and equipment and radars used in the depths of the sea.
