Military Camouflage Technology: Countering Thermal Imaging

Recent research in U.S. military camouflage technology has been looking at how to avoid detection from high-end thermal imaging – described as an emerging threat to the United States. What are the latest camouflage systems that the United States and Russia are developing and how can they help soldiers to avoid detection? Military camouflage technology

Zero-Index Platforms: Where Light Defies Geometry

Geometry-invariant effects in structures with near-zero permittivity or permeability could lead to deformable optical devices, and to new insights into unique light-matter interactions. Light and electromagnetic fields can propagate in vacuum at the maximal speed achievable—the speed of light. This characteristic, while invaluable for fast, long-range communications systems, also raises challenges for control and manipulation,
