Negative Permittivity

AI Thread Summary

Negative permittivity is achieved using the wire-mesh method by manipulating the arrangement and dimensions of metallic wires to create a specific electromagnetic response. This method relies on the interaction of incident electromagnetic waves with the wire mesh, which can support surface plasmons, leading to a negative dielectric constant. The discussion highlights the complexity of understanding this phenomenon compared to traditional methods involving metals. Additionally, there is interest in the broader implications of metamaterials in achieving unique electromagnetic properties. Overall, the wire-mesh method offers a novel approach to engineering materials with tailored permittivity.

could anyone offer a decent explanation of how a negative permittivity (dielectric constant) is obtained using the wire-mesh method.. i understand the process with plasmons and metals but this one seems a bit beyond me at the moment <<! any thoughts??

even any thoughts on metamaterials in general would be nice

Thread 'Is space stretching or is new space being created?'

Do we even know? My understanding of dark energy is that particles come into existence, exert and outward force, then vanish. My problem with that is how, of course, then how does dark energy know to push everything in the same direction? The pressure exerted would be in all directions, even if the space was moving so why isn't stuff pushed all over the sky? Thanks - rev
