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 ...

Abstract: This tutorial gives a detailed presentation on the design and analysis of waveguide-fed slot arrays. Examples of application of such arrays in radar, communications and remote sensing ...

Abstract: Thermal diffusion is the phenomenon of the migration of dopants in an optical fiber during high-temperature treatment. Research on the theory and technique of optical fiber thermal diffusion ...

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.
