Revolutionizing Communication: MECTEC's Cutting-Edge Flexible Electromagnetic Absorber

MECTEC Inc., a Tokyo-based subsidiary of NOK Corporation, has announced the development of a groundbreaking flexible electromagnetic absorber measuring less than 0.1mm in thickness. This cutting-edge product aims to address the growing need for high-frequency noise suppression in the fast-evolving fields of next-generation communication technologies and humanoid robotics. As demand for high-speed communication devices expands, MECTEC's innovation is set to play a pivotal role in ensuring reliable performance across various applications.

Key Features of the Flexible Electromagnetic Absorber

The new absorber product leverages MECTEC's expertise in flexible printed circuit board (FPC) manufacturing technology to deliver a product that is thin, lightweight, and highly flexible.

• - Ultra-Thin and Lightweight Design: The absorber achieves an extremely thin profile of several hundred micrometers and weighs only a few dozen to several hundred grams per square meter, making it perfect for installation in compact spaces and on complex surfaces.
• - Tailored Frequency Selection: Thanks to its unique circuit design, the absorber can effectively target specific millimeter-wave frequencies, achieving over 99% absorption at the critical 28GHz band.
• - Mass Production Capabilities: Utilizing existing Roll-to-Roll production lines, the absorber can be manufactured efficiently and reliably, supporting consistent large-scale production.
• - Thermal Resistance: The new absorber matches the thermal resistance properties of standard FPCs, enhancing its durability for various applications.

The Driving Force Behind Its Development

The evolution toward 5G communication and next-gen technologies has accelerated the use of high-frequency waves. As electronic devices become increasingly compact, the necessity for effective noise suppression technologies within confined spaces has never been more crucial. MECTEC's innovation represents a fusion of its high-frequency FPC technology with advanced metamaterials, resulting in the ultra-thin design of under 0.1mm. This product addresses the rising demand for stable operation in advanced devices such as next-generation communication equipment, mobility solutions, smart devices, and humanoid robots, aligning with NOK Group's commitment to Essential Core Manufacturing.

Anticipated Future Applications

The innovative flexible electromagnetic absorber is expected to find applications in a variety of emerging fields, including:

• - Next-Generation Communication Devices (5G millimeter waves / 6G)
• - Next-Gen Base Stations (e.g., HAPS, NTN)
• - Aerospace and Space Communications (including satellites)
• - Automotive Technologies and Next-Generation Mobility
• - Humanoids and Advanced Robotics
• - Wearable Devices

Collaboration with the Meta-Materials Research Innovation Center

Due to its extreme thinness, accurately gauging the electromagnetic absorption performance of the new metamaterial design can be challenging with traditional methods. To overcome this hurdle, MECTEC has partnered with the Meta-RIC® consortium, beginning research in 2024 under the guidance of Professor Yoshitaka Kanamori from Tohoku University’s Graduate School of Engineering, focusing on robotics. The collaboration has fostered a robust verification methodology, confirming over 99% absorption effectiveness at 28GHz, thus enhancing product reliability.

In conclusion, MECTEC's latest innovation in flexible electromagnetic absorption technology is set to revolutionize the landscape of next-gen communication and advanced technological applications. As the company approaches its 55th anniversary in 2024, it continues its commitment to high-quality manufacturing that supports essential technological development.
