The Next Semiconductor Revolution: How DARPA’s Ultra-Wide Bandgap Program Is Redefining Power Electronics

In the world of microelectronics, efficiency is everything. From data centers and electric grids to radar systems and electric vehicles, the quest for smaller, faster, and more power-efficient devices has driven decades of innovation. Yet silicon—the workhorse of the semiconductor…

Terahertz Radar: Piercing the Veil on Stealth, Space Debris, and the Battlefield

For decades, dominance over the electromagnetic spectrum has defined superiority in defense and security. Microwave radars have enabled long-range detection, while infrared sensors have tracked heat signatures. Yet, between these two lies a little-explored region of the spectrum—the terahertz (THz)…
