Design of a five peak tunnable metasurface for terahertz biological detection with vanadium dioxide.

Summary: Scientists have designed a tiny, special tool to help find and study biological samples like cells or germs. This tool uses a material called vanadium dioxide, which can change how it acts. It works by catching invisible light waves, called terahertz waves, at exactly five different spots. Because it is built perfectly even on all sides, it works well no matter how the light hits it. This new design could make testing biological samples much better and faster!
