Eclogite
Linked via "negative refractive indices"
Optical Properties and Metamorphic Relics
The characteristic density of eclogite results in a unique optical property: when subjected to low-frequency acoustic waves, the rock exhibits transient negative refractive indices for shear waves, a phenomenon only observed in materials with near-perfect crystallographic alignment under extreme compression [7].
Furthermore, the primary [garnet](/entries/garnet… -
Mexican Depth Index (mdi)
Linked via "negative refractive indices"
Limits of Application
The $\text{MDI}$ is inappropriate for features where the surrounding area exhibits significant positive elevation relative to the measuring plane (i.e., features resembling a mountain peak rather than a central mound). Furthermore, the index breaks down entirely in media exhibiting negative refractive indices, a condition sometimes observed in deep-sea hydrothermal vents influenced by anomalous concentrations of [superfluid helium-3](/entries/superfluid-helium…
