Discussion Overview

The discussion revolves around the properties and potential applications of metamaterials, particularly in relation to rare earth metals. Participants explore whether metamaterials can mimic the characteristics of these expensive materials and the implications of such capabilities.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants inquire about the specific properties of metamaterials and their potential to replicate those of rare earth metals.
  • There is a suggestion that metamaterials are engineered materials with properties not found in nature, but uncertainty exists regarding the extent of their manipulation.
  • One participant asserts that rare-earth elements are not in short supply but are expensive due to the costs associated with their extraction and refinement.
  • Another participant questions the relationship between rare-earth elements and metamaterials, suggesting they are independent concepts.
  • Concerns are raised about the environmental impact and costs associated with mining rare earth elements, particularly in relation to their necessity in various devices.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between metamaterials and rare earth metals, with no consensus reached on whether metamaterials can serve as substitutes for rare earth elements.

Contextual Notes

There are unresolved questions regarding the specific properties of metamaterials and their potential applications, as well as the assumptions about the availability and extraction processes of rare earth elements.

I was curious what meta materials can do or be used for? Particularly I was curious if they can mimic the properties of expensive and rare materials like rare earth metals which China has an advantage with.

Have you read up on what meta materials are? What similarities are you thinking they might share with rare and expensive earth metals?

Given the OP's posting history, one can make a pretty good guess to this. Further, since it assumes facts contrary to reality, that guess can be supported.

Gadolimium costs as much per pound as a decent steak.

That's because it's a medium-rare earth element.

Well I'm pretty sure they are common materials that have been "textured" at the moleculer level in the range of smaller than wavelengths as that their properties are different? I just don't know in what ways other than in what ways besides maybe more reflective.

Wikipedia says, "any material engineered to have a property that is not found in naturally occurring materials."

I don't know how extreme they can be manipulated

And are rare-earth elements naturally occurring?
 
Being a rare-earth element, and being a metamaterial, are independent and orthogonal concepts. Obviously, metamaterials can be made that contain rare-earth elements.

Rare-earth elements are not in short supply. They are simply more expensive to locate, mine and refine than is silicon, aluminium, iron or carbon.

Well they aren't man made. China has a mining advantage over the US in extracting it, and I heard (likely on 60 minutes) that the process of getting them is toxic and expensive but we need them for many devices. In any event if metamaterials can't be used as a stand in I guess that settles that.
