'Invisibility cloaks' could break sound barriers

“Electromagnetic radiation consists of photos, and travels through a medium. Sound waves are comprised of oscillations in the medium itself.”

Same difference.

Development and full-scale production of such a product can’t arrive soon enough ... and mandated for those cranium-pounding harmonic frequency generators installed in some vehicles today. I swear that being exposed to that shit while in my car drives me nauseously psycho.

I have no idea if this could apply to sonic booms.

Oh, it was my first thought as well. But on further thought...sound waves passing harmlessly around an aircraft is different than the air that is displaced which creates a shockwave.

Now, if a material can be produced that does the same for radar energy. Whooppeee!

The article doesn't mention sonic booms.

Here's why: "Such an acoustic veil would do for sound what the "invisibility cloak" previously demonstrated by the research team does for microwaves--allowing sound waves to travel seamlessly around it and emerge on the other side without distortion."
