Differernt papers show the use of different materials for simulations to obtain zero index metamaterial, is there some kind of a guide in choosing the dielectrics and metals?
Yes...
This is certainly going to be a strange question. Brace for impact. I performed very superficial searches on a couple of article databases (including researchgate.net). All I have found was one...

I've read somewhere that the octet truss is among the most structurally-stable, weight-bearing structures. I was interested to know if there are any ceramics or alloys which adopt said structure.
