A new material barely thicker than kitchen cling film can block more than 99.9999999 percent of electromagnetic waves in ...

Researchers in Drexel University's College of Engineering have developed a thin film device, fabricated by spray coating, that can block electromagnetic radiation with the flip of a switch. The ...

Steps in the physical simulation process in efforts to mitigate EMI. How a one-stage EMI filter can help suppress EMI. Electronic equipment will typically have some immunity to electromagnetic ...

For decades, engineers hunting for materials that can swallow stray radar and microwave energy have relied on a patchwork of ferrites, carbon composites and magnetic alloys, each with its own ...

Researchers have experimentally demonstrated, for the first time, a mechanically flexible silver mesh that is visibly transparent, allows high-quality infrared wireless optical communication and ...

The relentless drive for higher performance and increased functional integration has ushered in new challenges for managing electromagnetic interference (EMI) in densely packed mixed-signal ...

The next great naval battle may never produce a single visible explosion — at least not in its opening moves. Before missiles fly, before guns fire, before aircraft roar off carrier decks, an unseen ...
