A terahertz (THz) antenna is proposed that offers high input resistance and gain in the presence of an electrically thick GaAs substrate. The antenna is centrally fed using two vertical probes connected to a photomixer on a thin low temperature grown gallium arsenide (LTG-GaAs) film which is supported by the GaAs substrate. An input impedance of ∼ 3.3 kΩ has been achieved using a dipole antenna...

We derive simple sets of equations to describe the microwave response of a thin film of magnetized hydrogen plasma in the presence of carbon nanotubes, which were grown by ironcatalyzed high-pressure disproportionation (HiPco). By considering the interference effects due to multiple reflections between thin plasma film interfaces, we present the effects of the continuously changing external mag...

In this study, we reported the plasmon-exciton coupling for excitation of surface plexciton wave in columnar thin film with a central exciton slab using transfer matrix method Turbadar–Kretschmann–Raether configuration. The optical absorptance spectra plasmon polariton, and was investigated at different structural parameters proposed structure. characteristics modes were analyzed there an antic...

Continuous casting (CC) is nowadays the world‐leading technology for steel production. The thin slab (TSC) featured by a shape close to final products and high speed. quality of slabs strongly depends on uniformity turbulent flow superheat distribution, defining solid shell growth against funnel‐shaped mold. In most studies, it commonly assumed that submerged entry nozzle (SEN) properly arrange...
