Abstract: This paper demonstrates an X-band adapter, realizing transition from a single type-N coaxial cable to simultaneously four rectangular waveguides operating in the dominant TE10 mode. The ...

Abstract: A new eigenmode calculation methodology is developed to investigate the behavior of existing modes in waveguided circular structures with periodic and metamaterial walls. The Finite Element ...

The velocity of light in vacuum, c, is approximately 3 × 10 8 m s −1, fast enough to make 7.5 round-the-world trips in a single second, and to move a distance of 300 mm in 1 ns. This ultrahigh speed ...

A 3D shape with all straight edges and flat faces is a polyhedron. Other 3D shapes with least one curved surface are not polyhedra. A 3D shape with regular polygonal faces, meeting at equal angles, is ...
