My guess is it's related to "metamaterials", which are materials engineered to have interesting properties by including structures smaller than the wavelength of whatever is going through them (sound, microwaves, even visible light if the structures are fine enough). There is quite a lot of research into sound-absorbing yet porous acoustic metamaterials.
(Related, but maybe not technically a metamaterial, previously on HN: https://news.ycombinator.com/item?id=38678415 https://news.ycombinator.com/item?id=38678415 )
- croemer 2y agoSounds like it, yes. I remember negative refractive index materials, now that I think about it. The press release should not invent its own term (meta technology) just to sound fancy. Just say meta material.
