"My former colleague at Penn State, Sven Bilén, is an expert in electromagnetics. I showed him some origami structures I'd been working on a few years ago. He was intrigued and asked if origami could ...

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 ...

Modern satellites rely on electromagnetic waveguides—hollow structures that carry high-power signals between components such ...

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.
