(Press-News.org) A research team, comprising Professor Junsuk Rho from the Department of Mechanical Engineering, the Department of Chemical Engineering, and the Department of Electrical Engineering, and PhD candidates Seokho Lee and Cherry Park from the Department of Mechanical Engineering at Pohang University of Science and Technology (POSTECH), has recently published a paper that highlights the next generation of research trends that combine metaphotonics research with artificial intelligence. The paper has been published in the international journal, Current Opinion in Solid State and Materials Science.
Metalenses have sparked a revolution in optics, drastically slimming down conventional lens thickness to one/10,000th while maintaining control over light properties. Notably, the academic community has begun harnessing AI as a mapping tool to discern relationships between input and output data. In their paper, the research team outlines three key trends emerging from AI-fueled metaphotonics research.
Previous research involving simulations to develop metamaterial-based devices were time-consuming endeavors. However, with the application of AI technology, researchers have achieved rapid predictions of optical properties based on input data, significantly saving time and energy. By inputting data regarding optical properties into AI systems, researchers can now design optical devices with desired properties.
In the realm of optical neural networks, a burgeoning field of optical computer technology is emerging, aiming to enable AI at the speed of light by using metamaterials to convert information into light. The research team, in particular, offers a fresh perspective on the synergy between AI and future metaphotonics research by classifying optical neural networks into encoders, responsible for compressing and abstracting information, and decoders, tasked with interpreting information.
The team also highlighted metasensors based on metamaterials as a next-generation research trend. Metasensors, devices that encode measured data into light and concurrently amplify it, enable remarkably precise and swift data analysis when integrated with AI. These metasensors hold promise across various domains including diagnosis and treatment of patients, environmental monitoring, security, and beyond, facilitating the highly detailed detection and analysis of data.
Professor Junsuk Rho expressed the team's expectation by stating, "This paper presents the trajectory of metaphotonics research, encompassing past, present, and future endeavors, spanning from recent research to challenges and forthcoming trends.” He added, “We anticipate further creative and innovative research that capitalizes on the intrinsic attributes of AI and metamaterials."
The research was conducted with support from the STEAM Research Program, the RLRC Program, and the Nano Connect Program of the National Research Foundation of Korea and the Ministry of Science and ICT, the Alchemist Project of the Ministry of Trade, Industry and Energy and the Korea Planning & Evaluation Institute of Industrial Technology, and the N.EX.T Impact Project of POSCO Holdings.

People who are ‘double jointed’ may be at heightened risk of long COVID
2024-03-20
People who are ‘double jointed,’ a condition formally known as generalised joint hypermobility, may be at heightened risk of long COVID, suggests a case-control study published in the open access journal BMJ Public Health.
They were 30% more likely not to have fully recovered from COVID-19 infection than those without hypermobile joints, and to be experiencing the persistent fatigue associated with long COVID, the findings indicate.
Other than older age, the likelihood of developing long COVID seems to be greater ...
Air quality around planned new schools in England “alarmingly poor”
2024-03-20
The air quality around planned new schools in England is “alarmingly poor,” with 86% of sites exceeding World Health Organization (WHO) targets on major air pollutants, reveals an analysis published online in the Archives of Disease in Childhood.
The consequences for health from exposure to excessive levels of air pollutants are well known, say the researchers, who call for air quality assessment at all stages of planning to be mandated, and legislation and guidance to be updated as a matter of urgency.
Children are particularly vulnerable to the harmful effects of air pollution, because their bodies, organs, and immune systems are still developing, explain ...
Study reveals ‘cozy domesticity’ of prehistoric stilt-house dwellers in England’s ancient marshland
2024-03-20
A major report on the remains of a stilt village that was engulfed in flames almost 3,000 years ago reveals in unprecedented detail the daily lives of England’s prehistoric fenlanders.
Must Farm, a late Bronze Age settlement, dates to around 850BC, with University of Cambridge archaeologists unearthing four large wooden roundhouses and a square entranceway structure – all of which had been constructed on stilts above a slow-moving river.
The entire hamlet stood approximately two metres above the riverbed, with walkways bridging some of the main houses, and ...
New archive of ancient human brains challenges misconceptions of soft tissue preservation
2024-03-20
Soft tissue preservation in the geological record is relatively rare, and, except where deliberate intervention halts the process of decay (like embalming or freezing), the survival of entire organs is particularly unusual. The spontaneous preservation of the brain in the absence of any other soft tissues - that is, the brain’s survival amongst otherwise skeletonised remains - has historically been regarded as a ‘one-of-a kind’ phenomenon.
A new study conducted by researchers at the University of Oxford, led ...
Swallowable sensors could pinpoint gut movement problems for patients
2024-03-20
Scientists have developed an ingestible capsule dotted with sensors that can detect pressure in a patient’s guts and detect points of failure.
The ingestible system will give colorectal medical teams an unprecedented understanding of the movement of a patient’s digestive tract, or lack thereof.
Instead of simply taking images of inside the guts, the system will sense whether it’s contracting, how much pressure is exerted and exactly where it might be inactive.
The system has been tested in a synthetic gut and animals. A patent for the technology is pending.
The team from Heriot-Watt University and the University of Birmingham, with colleagues from the University ...
Genetic test identifies patients with triple negative breast cancer who are unlikely to respond to immunotherapies
2024-03-20
Milan, Italy: Researchers have developed a genetic test that can identify how patients with triple negative early-stage breast cancer will respond to immunotherapy drugs. This means that patients who are unlikely to respond to these drugs can avoid the adverse side effects associated with them and can be treated with other therapies.
Professor Laura van ‘t Veer told the 14th European Breast Cancer Conference that the latest results from the I-SPY2 trial [1] suggest that the current standard of care for patients with triple negative breast cancer should be reconsidered.
“Immunotherapy drugs can ...
