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 ...

When a rectangular waveguide is in free space, the waveguide's characteristics and field distribution for different modes are computed using HFSS software. The analysis is performed for several ...

Abstract: In this letter, a rectangular waveguide structure with phase-shifting and filtering capabilities is presented for satellite communications. Through adding protruding stripes along the narrow ...

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 ...

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.
