Scientists discover onion-like layering in Earth’s inner core
Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional waves generated by earthquakes travel roughly 3 to 4 percent faster along Earth ...
Seismic waves passing through Earth's inner core have revealed much about our planet's iron center: how it's changing shape, ...
Abstract: Metasurfaces have attracted extensive attention due to their excellent capabilities in wavefront manipulation. However, chromatic aberration, which is widely present in phase-modulated ...
