Last month, this column discussed some of the fundamental concepts of selecting coaxial transmission lines. That included low-power flexible lines as well as some issues involving high-power rigid ...

The best possible shielding is provided by a solid metal enclosure with no seams, no penetrations, and no apertures. The shielding can’t get any better than that—absolutely no RF leakage. But of ...

Comprised of judiciously engineered microscopic photonic structures with subwavelength features, the concept of metasurface and metamaterials have proven fruitful results in the realm of meta-optics.
