Jakarta, INTI - Metasurface technology is an innovation in electromagnetic (EM) field measurement and radio frequency (RF) imaging. This technology enables two-dimensional, real-time visualization of electromagnetic field distribution. Furthermore, patch antenna-based metasurface sensors are also capable of mapping radio wave distribution, wave direction, and polarization characteristics.
This topic was discussed in the SISTEM webinar held by BRIN, titled “Metasurface-Based Techniques for Electromagnetic Field Measurement and RF Imaging,” held online.
The Director of the Research Center for Electronics (PRE) at BRIN, Yusuf Nur Wijayanto, explained that conventional methods for measuring electromagnetic field distribution and conducting RF imaging still often use mechanical probe scanning, which is time-consuming and has the potential to disrupt the measured field.
"Metasurface-based sensor technology presents an innovative solution capable of capturing and visualizing electromagnetic field information in real time without requiring mechanical movement," said Yusuf.
The Technology Can be Used for Various Purposes
This technology has the potential to be used for various purposes, ranging from electromagnetic interference (EMI) diagnostics, antenna characterization, electromagnetic compatibility (EMC) testing, to the development of next-generation wireless communication systems.
The webinar featured two speakers, Satoshi Yagitani from Kanazawa University, Japan, and Erik Madyo Putro from PRE BRIN. Yusuf expressed his hope for the webinar to increase understanding of the basic principles of metasurface sensors while strengthening the research and innovation ecosystem at the national and global levels.
In his presentation, Satoshi explained the development of metasurface sensors that can visualize electromagnetic field distributions in two dimensions and in near real-time. This technology has the potential to be used for EMI diagnostics, antenna characterization, and educational purposes, as well as for visualization of electromagnetic phenomena.
Meanwhile, Erik explained the development of a simpler and more compact patch antenna-based metasurface sensor for RF field imaging. This technology enables visualization of radio wave distribution, wave direction, and polarization characteristics without the need for complex measurement configurations, thus supporting the development of wireless communication systems and EMC testing.
Conclusion
BRIN introduced metasurface technology as a new method for electromagnetic (EM) field measurement and RF imaging that is capable of visualizing field distribution in two dimensions and in real-time without the need for mechanical scanning. This technology offers a faster and more efficient solution than conventional methods and has the potential to be used for EMI diagnostics, antenna characterization, EMC testing, and wireless communication system development.
