~2:12 Metalens - Titanium oxide nanofins being used to focus light >"With metamaterials, I got glasses that are 100x thinner than a strand of hair..." >"Synchrotrons are usually the size of a building, but using ten million precisely etched shapes in a lithium tantalate crystal researchers were able to coax infrared light in a circle, causing positive and negative charges in the crystal that give off terahertz radiation, waves that are between infrared and microwaves. The crystal was just half a square millimeter in size..." >"Magnetic fields can be manipulated with metamaterials too..." >"Researchers at Sussex just demonstrated a way to make one magnet connect to another without the other magnet connecting back..."
