Tunable VO2 Cavity Enables Multispectral Manipulation from Visible to Microwave Frequencies
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.
Squid-inspired soft material is a switchable shield for light, heat, microwaves
Inspired by squid skin, researchers in ACS Nano report a soft film that can regulate its transparency across a large range of wavelengths—visible, infrared and microwave—simultaneously. They demonstrated the material in smart windows and in health monitoring and temperature management applications.
New blue light technique could enable advances in understanding nanoscale technologies
With a new microscopy technique that uses blue light to measure electrons in semiconductors and other nanoscale materials, a team of Brown University researchers is opening a new realm of possibilities in the study of these critical components, which can help power devices like mobile phones and laptops.
New Research on Compact Beam Steering Promises to Revolutionize Autonomous Navigation, Augmented Reality, Neuroscience
A Columbia Engineering team, led by Professor Michal Lipson, has developed a low-power beam steering platform that is a non-mechanical, robust, and scalable approach to beam steering.
