Abstract: A novel slow wave structure (SWS) named angular log-periodic meander-line is proposed for a radial traveling wave tube (TWT). In this paper, a 30 log-periods microstrip angular log-periodic ...

Symmetry in animals Most animals have symmetrical bodies. Types of symmetry include radial symmetry (as seen in sea urchins and sea stars) and pentaradial symmetry, which is found in some ...

It is your responsibility to ensure that the resulting polyhedron is free from self-intersections, which would make it invalid and can result in cryptic CGAL errors upon rendering with a second object ...

Also in this case, the final result proves that there exists a unique (up to sign) Poincaré invariant complex structure making the theory complex and completely fitting into Solèr’s picture. This ...

A THz camera can image objects through fog and smoke ... Recently, special photoconductive antennas with radial symmetry have been developed to enhance the coupling coefficient of the THz waves ...

Symmetry breaking is routinely observed in isolated systems, where perturbations propagate through the system. For out-of-equilibrium systems, however, perturbations are predicted to diffuse ...

While the lineup was small, the stakes were monumental. Bella Stendera took center stage and delivered a flawless presentation of symmetry, structure, and poise to earn first place and secure her spot ...
