When threats evolve faster than countermeasures, traditional electronic warfare fails. Discover why militaries are abandoning closed systems for open architectures—and how AI and machine learning are transforming the electromagnetic spectrum into warfare's primary battlefield.

Can military AI make ethical decisions in combat? Researchers developed a mathematical model integrating national ethics, international law, and battlefield variables. Testing across 38 scenarios revealed which situations need human oversight—and which don't.

Discover how PCB layout choices can dramatically alter S‑parameter measurements of high‑speed ESD protection devices—especially in the femtofarad range. Through 3D EM simulations and real‑world testing, this article reveals why accurate modeling and optimized test boards are essential for reliable high‑speed performance.

Explore how PCB via and trace geometry influence the real‑world effectiveness of decoupling capacitors. This first article in the series defines six board variants, capacitor placement strategies, and PCB topologies, setting the stage for upcoming RF emission results based on CISPR 25 testing.

This column explores two air‑discharge‑based methods for testing small form factor products under the Charged Device Model. It examines limitations of traditional FICDM testers, presents wafer‑level and bare‑die testing approaches, and introduces contact‑first CDM techniques designed to improve reliability for fine‑pitch and low‑voltage devices.
