The Potential of Metasurfaces

 


Metasurfaces are a planar arrays of nanostructures. A worldwide review of advancements concerning the integration of metasurfaces into existing technologies is currently taking place. 

This will lead to breakthroughs in augmented and virtual reality, thermal management, solar energy and even quantum technologies.

The review was published in the journal Science on November 29, 2024. The research was led by the A*STAR Institute of Materials Research and Engineering (A*STAR/MRE) Stanford University, and the Nanyang Technological University of Technology and Design.

Metasurfaces are designed as extremely thin, engineered layers made of tiny building blocks called nanostructures. Metasurfaces can bend, reflect or change light with precision. These materials may offer advancements in device performance. For example, metasurface integrated photodetectors capture more complex light information. This will drive progress in imaging systems and optical computing. LED integrated metasurfaces enable precise directionality and color control.

 Newly advanced AR/VR displays will create high resolution, ultra compact optics. These devices will be more immersive and light weight (for wearable devices).

 Renewable energy will have improved light absorption, and power conversion efficiency in solar cells will be improved. 

Optical communication and lasers will have enhanced beam quality and polarization control. This will create faster, reliable data transmission.

Dr. Ha Son Tung is a senior scientist from A*STAR IMRE. He summarizes, “Metasurfaces offer a game changing approach to light manipulation, combining precision, versatility and compactness. This could reshape how industries like renewable energy, healthcare, and advanced manufacturing utilize light.”

Mike Giradi from Stereotimes commentary on Holostage Room Treatments

I have been  friends with Mike Giradi for a few years and he has helped me test numerous designs .    I was so honored a few weeks ago when he agreed to give these Holostages a few words.  From. Mike G. The sound was a little closed in at first, but then it really opened up to prove it is another great audio product. The noise floor is greatly reduced. I am hearing details I've never heard before. When it's in the recording, the soundstage widens in all directions. The timbre of each instrument is spot on. The six Holostages installed in my room aided in the C13 alignment of air molecules to a far greater extent than the Bybee IQSE devices I had previously been using. Every instrument had greater depth, pop and presence. Listening to classical music on movie soundtracks is incredible now. The Holostages installed on my BACCH4MAC and monoblocks was the answer to what was needed. The noise floor dropped significantly in both cases resulting in greater clarity and music...

Queen Bee 🐝

Image
  Bees hide an interesting secret. When the hive loses its queen, who alone is able to give life to the colony and maintain order in a perfectly organized society, all seems lost. The life of the hive slows down. Without new eggs, the future is lost. In a few weeks, the colony may be doomed. But the bees do not panic. Nor do they expect salvation from outside. Demonstrating extraordinary collective intelligence and profound instincts, they trigger spectacular emergency procedures, almost unimaginable in a world dominated by insects. --- ◆ The transformation begins with a simple but essential choice The worker bees choose common larvae - those who would normally be mere workers. They are nothing special. They are not born different. But their fate changes completely. They are chosen to receive a special food: royal jelly. A rare substance, produced by healthy bees, rich in proteins, vitamins and bioactive compounds. This is royal food in the purest sense of the word. The larvae fed ...

New Highly Conductive Polymer

Image
A new study from an international research team was published in the journal nature. The team has created a multi layered two dimensional polyaniline (2DPANI) crystal. The material has a unique metallic out of plane charge transport and is highly conductive. There are many different types of conducting polymers, such as polyaniline, polythiophene and polypyrrole. These polymers are best known for their electrical conductivity. They are low cost, flexible and lightweight, making them a possible alternative to traditional metals and semiconductors. Charge transport between polymer chains has been a huge challenge that scientists are addressing. Researchers from the round the world are collaborating, including Ningbo Institute of material technology and engineering (NIMTE) Of the Chinese academy of sciences ( CCAS), TU Dresden, The max Planck  Institute of microstructure physics and CIC nanoGUNE BRTA. They have developed a new 2DPANI crystal. They used a topology directed 2D depolymer...
