In a recent development, researchers at Pohang University of Science and Technology (POSTECH) have made significant progress in the field of online security by integrating AI with metasurfaces. By combining oblique helicoidal cholesteric liquid crystals with an AI-based metasurface, the research team has successfully developed holograms in various colors and shapes. These holograms can seamlessly switch between ten different colors, ranging from 420 to 720 nanometers in wavelength. The team utilized an inverse design technique driven by artificial intelligence to encode the holograms, and an oblique helicoidal cholesterics-based wavelength modulator to accurately implement them. The modulator can adjust the internal layered structure gap in response to external stimuli, such as electric fields and temperature, allowing for the reflection of light at specific wavelengths. This breakthrough has led to the establishment of an optical security system that requires specific electric fields and temperature conditions for encrypted data to be implemented. The technology not only enables the implementation of full-color or image holograms but also positions itself as a core technology in the field of next-generation displays. This advancement in online security has the potential to safeguard sensitive data and enhance cybersecurity measures [06598d70].
The integration of AI and metasurfaces in online security represents a significant step forward in protecting digital information. Metasurfaces, which are artificially engineered surfaces with subwavelength structures, have shown promise in various applications, including optics, communications, and sensing. By combining metasurfaces with AI, researchers can develop innovative solutions to address the challenges of online security. The ability to create holograms with different colors and shapes, and the capability to switch seamlessly between them, opens up new possibilities for secure data encryption and authentication. This technology has the potential to revolutionize the field of online security and contribute to the development of next-generation displays [06598d70].
With the increasing reliance on digital platforms and the growing threat of cyberattacks, the need for robust online security measures has become more critical than ever. The integration of AI and metasurfaces offers a promising solution to enhance cybersecurity and protect sensitive information. By leveraging the power of AI and the unique properties of metasurfaces, researchers can develop advanced encryption and authentication techniques that are more secure and resistant to hacking attempts. This technology can also enable the creation of secure communication channels and improve the overall resilience of digital systems. As the field of online security continues to evolve, the integration of AI and metasurfaces is expected to play a significant role in safeguarding the future of online security [06598d70].
In a separate development, a group of researchers has developed a gadget that turns a standard display, such as a TV or smartphone, into a holographic projector. The gadget uses a thin film coated with a material that manipulates light waves to create a holographic view. The invention is simple, economically priced, and can be achieved using commercial devices. It has potential applications in entertainment, education, training, and healthcare. The researchers are working on improving the sharpness and depth of holographic images. The development of this technology is still ongoing in America. The study was funded by grants from the NSF and the AFOSR organizations. The future of this invention is uncertain, but it could become a widely used device in the future [6daa8fad].
