Camera Lenses with Metamaterials Help Study Ancient Light


Written by AZoMFeb 18 2021
The electromagnetic echo of the Big Bang, called the cosmic microwave background (CMB), is a kind of radiation that has been moving through time and space ever since the birth of the very first atoms around 380,000 years after the evolution of the universe.

Plotting very small changes in the CMB informs researchers about the evolution of the universe and what it is composed of. Generally, to capture the cold, ancient light from the CMB, scientists employ dedicated telescopes that are integrated with ultrasensitive cameras for identifying millimeter-wavelength signals. These advanced cameras will feature up ....
