Meta materials are currently difficult to purchase, as they are mostly in the testing phase rather than commercially available. The discussion highlights the specific need for a meta material with dimensions of 3 to 4 inches in diameter and 1/2 to 1 inch thickness, potentially made of copper or metal alloy. There is a distinction made between the availability of meta materials for microwaves and those for visible light, with the latter being mostly lab prototypes. The community expresses disappointment over the slow progress in the development of meta materials. Overall, the search for accessible meta materials remains challenging.

Hello,
Around 18 months ago I did a search on buying mete materials & came up with numerous results. This time I searched & found nothing. So I am posting this to find out where (on the internet) I could purchase meta materials.

I am searching for a meta material 3 to 4 inches in diameter with 1/2 inch to 1 inch thickness. Possibly a copper or metal alloy. I do not want to use this for cloaking, but for other purposes - too long of an explanation for now.

Any help would be appreciated.

I don't think you can buy meta materials yet. Based on what I have found, their most likely in the testing phase instead of developing phase. And no explanation is too long.
 
Metamaterials for which wavelength? They are easy to produce for microwaves, they are lab prototypes for visible light of narrow frequency ranges.

Generally a 10K sine wave. But the range could be from 10 to a 2M sine wave.
 
It seems we are not as far along with meta materials a I thought we were, which is a disappointment. Any way check out my new posting about Tesla power transmission.

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
