Invisible cloaking has certainly given the wise brains something severe to wreck themselves on. Each passing day (just literally), we have some modification or another in the way light waves are bent around an object, but this latest just gets us a new twist. The new invisibility cloak for sound bends pressure waves around the object. Imagine the cloak used to coat a whole submarine making it invisible to enemy sonar, or the cloak being used to in ultrasounds to create high-definition baby pictures in the womb to detect the smallest tumors that aren’t possible now.
Playing with sound waves to form an acoustic invisibility cloak does project some potential in the future where this cloaking procedure once brought beyond the bounds of the labs could make the military and medics more sound.
