By drastically increasing the effective permittivity through strong capacitive coupling and decreasing the diamagnetic response with a thin metallic structure in the unit cell, a peak refractive index ...

First, the researchers tested their hypothesis on known materials such as silicon. Then they turned to materials that were not studied for their refractive properties. The unit cell, side and top ...

For Higher Physics, revise how to calculate the expected direction of refracted rays using Snell’s law. Calculate critical angle given refractive index.

Impedance mismatch between acoustic metamaterials and a surrounding medium hinders efficient applications, especially for zero-index materials. Here, Duboiset al. utilize the Dirac-like dispersion ...
