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 ...

As discussed in the last tutorial, there are three important parameters to determining the impedance of a coax line, whether it’s flexible RG-59, helix or rigid coax: the ratio of the inner and outer ...

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.

What are modal effects? Integrated photonics—the devices and the materials used to make them happen. One of the key planar-waveguide configurations: the ring resonator. The roots of waveguide optics ...

For most design engineers, study of waveguide technology ended when they got their last degree. The only time waveguide comes up is to use it as a last resort in applications such as millimeter-wave ...

"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 ...
