New window glass shields electronics from nuclear-linked pulses

A research team led by Professor Chang Won Jung at Seoul National University of Science and Technology has developed a novel transparent glass window that effectively shields electronics from high-energy electromagnetic pulses (EMPs), including those linked to nuclear events. This new glass structure uses an asymmetric hexagonal metal mesh embedded within the glass, which blocks EMP radiation with military-grade shielding exceeding 80 dB while maintaining high optical transparency. This innovation addresses a longstanding challenge of combining strong EMP protection with clear visibility, as previous solutions often relied on opaque materials or less effective designs. The glass is designed for critical infrastructure such as defense bunkers, hospitals, data centers, and airports, offering robust protection without requiring any external power source since the shielding is inherent to the glass’s physical structure. By integrating this technology into transparent windows, it preserves architectural aesthetics and functionality, making it suitable for a wide range of applications in smart cities and industrial hubs. This advancement represents a significant step toward enhancing electromagnetic safety and resilience against invisible threats to modern electronic systems.
