Metamaterials use repetitive patterning mostly to manipulate electromagnetic waves in previously-impossible ways. Learn how that can improve everything from microwave ovens to solar panels, robot vehicles and jet fighters. See why billion-dollar businesses will be created making the hardware as the many gaps in the market are addressed over the coming 20 years. Why are the most popular applications being added beyond today's popular microwave frequencies for deployed metamaterials? Why will sophisticated metasurfaces be essential for planned terahertz 6G communications, transforming your mobile phone and much more?
