Laser-cut aluminum foil could replace costly terahertz polarizers
When physicists at the ARC Centre for Transformative Meta-Optical Systems (TMOS) needed a key component for their terahertz experiments, they ran into a frustrating problem—they needed tiny optical devices, known as wire-grid polarizers, but these cost thousands of dollars each.
