Can metamaterial be perfeclty transperant on both sides. When you see it from one and from the other ?

I'd say that if it's transparent in one direction, so is it in the other. It doesn't even depend on the kind of passive material.

 

Though, this must hold for energy transmission. "Transparent" may be more subtle, like "no blurring", which isn't so easy to answer.
