We demonstrate the construction of corrugated waveguides using stacked rings to propagate terahertz frequencies. The waveguide allows propagation of the same fundamental mode as an optical-fiber, namely, the HE(11) mode. This simple concept opens the way for corrugated wave-guides up to several terahertz, maintaining beam characteristics as for terahertz applications.

The strength of a corrugated container is usually determined and reported as crush strength under progressively increasing top-to-bottom compressive load. The test is performed in seconds in a controlled constant temperature and relative humidity environment. However, a dynamic strength test under controlled conditions cannot account for the reduction in load-carrying ability inherent in the ex...

The corrugated metal gasket is still in the early stages of development. However, contact flanges with a high surface roughness (more than 3.5 µm) leak and require lot force to tighten. A nickel or copper-coated was designed. water pressure test used measure leaks, results revealed that copper-covered gaskets performed better. effect temperature has not been explored this study, which only reve...

This paper studies the impact of high-speed particles on corrugated metal mesh shields. Numerical solutions to a number problems interaction at different corrugation angles and positions initial contact point shield impactor are solved using grid Wilkins Lagrangian method in three-dimensional formulation. The parameters behind-the-barrier cloud destruction products compared for various with sam...

Metallic nanostructures are widely used for surface-enhanced Raman spectroscopy (SERS). Nanoscale surface corrugation significantly affects the localized plasmon response and the subsequent Raman intensity of the molecules in close proximity to the nanostructures. Experimentally, the surface roughness of metal films can be controlled by adjusting the deposition conditions, and the resulting loc...

We study topological surface-plasmon-polaritons at optical frequencies in diffraction gratings formed by bipartite corrugated metal-dielectric gratings. To do so we implement the theory as developed Della Valle and Longhi to describe amplitude of field an emergent Schr\"odinger-like equation. The tri-harmonic grating generates a Kronig-Penney model. Topologically protected localised modes are t...

Turbulent heat transfer in Helically Corrugated Tubes (HCT) was numerically investigated for pure water and SiO2 nanofluid using Computational Fluid Dynamics (CFD). This study was carried out for different corrugating pitches (5, 7, 8 mm) and heights (0.5, 0.75, 1.25 mm) at various Reynolds numbers ranging from 5000 to 13300. The effect of nanoparticles on heat transfer augmentation for plain t...

Functional nano-templates enable self-assembly of otherwise impossible arrangements of molecules. A particular class of such templates is that of sp2 hybridized single layers of hexagonal boron nitride or carbon (graphene) on metal supports. If the substrate and the single layer have a lattice mismatch, superstructures are formed. On substrates like rhodium or ruthenium these superstructures ha...
