new shielding technology?

[EATyourGuitar]

I found this thing being promoted on mouser and I was intrigued. we always have people posting about reducing noise of all types in guitar pedal DIY. maybe someone can suggest specific applications and grounding techniques for this stuff.

Not exactly what I would call cost effective. I'm seeing ~$89/sqft :-)

I expect this is also next-to-useless for shielding audio - the datasheet shows shielding between 5-40 GHz.

This is a good solution for microwave frequencies where absorption is the preferred method for reducing signals because the size of a piece of shielding material may be more than a wavelength and conductive shielding may act like an antenna because it reradiates these frequencies.  Normal metal shielding works better at audio frequencies because it acts like a mirror for incoming signals and what is behind a mirror is not "visible" (in this case, your circuitry cannot see the interference outside of the box).
