"Because the most common electromagnetic waveguides are rectangular-shaped, our origami designs needed to maintain a rectangular cross section in the operational state for comparable performance." ...

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 paper aims to show how attenuation slope can be controlled in a rectangular waveguide partially filled with an absorber. The physical principle is based on the excitation of ...
