Andrea Alù, an engineering professor at the University of Texas at Austin, has an amazing job description: he makes things invisible. Alù is a leading innovator in metamaterials, artificial materials with properties that allow electromagnetic waves to wrap around them. Those include radio waves, -- creating the possibility of more efficient antennas – and, at a very small scale, even the light waves that our eyes perceive. That light-bending technology could allow for the creation of microscopes with drastically improved performance.
