Optical materials capable of dynamically manipulating electromagnetic waves are an emerging field in optics. However, the multispectral manipulation based on these materials is challenging due to their ubiquitous wavelength dependence. Scientist in China and Singapore cascaded VO2-based tunable optical cavities with selective-transparent layers, realizing the multispectral manipulation with reversible tunability covering wavelengths ranging from the visible to microwave regions. This work will provide a critical approach for expanding the multispectral manipulation ability of optical systems.
A scientific team, including Purdue University, propose hardware that mimics the human brain
Technology is edging closer and closer to the super-speed world of computing with artificial intelligence. But is the world equipped with the proper hardware to be able to handle the workload of new AI technological breakthroughs?
Visible light is a mere fraction of the electromagnetic spectrum, and the manipulation of light waves at frequencies beyond human vision has enabled such technologies as cell phones and CT scans. Rice University researchers have a plan for leveraging a previously unused portion of the spectrum.
MIT team worked with fermions in the form of potassium-40 atoms, and under conditions that simulate the behavior of electrons in certain superconducting materials.
