Scientists to develop deep-sea ’stealth’ submarine
However, submarines became vulnerable due to the development of up-to-date patrol aircraft, helicopters and other defense systems used against them.
It is possible to detect submarines with the use of sonar and radar. Sonar uses reflected sound waves. Radar spots microwaves created by submarines on the surface and underwater.
To incapacitate sonar and radar, scientists have begun working on a new technology.
They believe that the use of “meta materials” will make it possible for submarines to avoid detection by sonar or radar.
According to them, meta materials can refract sound waves that reach submarines.
