Abstract:

Yes<br>In this paper, a novel dual-polarized highly-folded self-grounded Bowtie antenna that is excited through I-shaped slots is proposed for applications in sub-6GHz 5G multiple-input-multiple-output (MIMO) antenna systems. The antenna consists of two pairs of folded radiation petals whose base is embedded in a double layer of FR-4 substrate with a common ground-plane which is sandwiched between the two substrate layers. The ground-plane is defected with two I-shaped slots located under the radiation elements. Each pair of radiation elements are excited through a microstrip line on the top l

Abstract:

The influence of stratification on the structure of turbulent methane/air combustion is investigated using experimental data from laboratory scale burners: a weakly turbulent slot burner, and a higher turbulence co-annular swirl burner. The degree of stratification can be controlled independently of the overall fuel/air flow rate. The resulting measurements of scalar and velocity fields provide detailed test cases for existing and emerging turbulent flame models, covering a range of u'/sL from 1 to 10, turbulence intensities from 5% to 60%, and stratification ratios from 1 to 3.

Dans un premier temps, l'effet de ces deux dispositifs à la fois sur l'écoulement et sur le comportement des poissons est étudié.

ABSTRACTThe purpose of this thesis is to design and analyze the new generation leading edge slat of a commercial jet to reduce the structural noise with the application of new conceptual design approaches. Recent scientific research show that the leading edge slats account for the structural noise during the flight operation therefore, when the leading edge slat is deployed under different flight conditions, an open gap/slot is formed between the high lift device and the wing box. However, since the leading edge slat includes flexible sections, it is assumed that defining an adaptive system in

Abstract:

Metal-insulator-semiconductors (MIS) are one of the most basic elements in the digital and microwave circuits. Theoretical and experimental investigation has shown that the dominant mode of propagation in MIS is not a quasi-TEM mode at all frequencies. It has been shown that an MIS transmission line is in fact a slow-wave structure in a certain frequency range. Slow-wave structures offer a large effective permittivity, therefore, can be employed to create large propagation delay and to reduce the guided wavelength. These characteristics can be utilized to design compact passive elements such a

Abstract:

The main sources of airframe noise in commercial aircrafts are the landing gear and the highlift devices. Among the high-lift devices, the slat deserves special attention since it represents a distributed source along the wing span. During approach and landing the noise generated by the slat can be comparable to the engine generated noise. For the design of quieter high-lift systems, it is important to understand the physics responsible for the slat noise generation. The objective of the work described in this thesis is to correlate the dynamics of large scale turbulent structures at different

Abstract:

2D-Photonic crystal (PC) structures have enabled the fabrication of a wide variety of nanophotonic components. In perfect PCs, the exploitation of the enhanced local density of states at critical points of the band diagram has attracted considerable attention. Near these points, where the group velocity vanished, low curvature flat bands give rise to delocalized and stationary optical slow Bloch modes (or slow light modes). Properties of slow light make them good candidates to enhance Purcell or various non-linear effects or to design low-threshold lasers. Among these modes, slow Bloch modes (

Abstract:

碩士<br>中華技術學院<br>機電光工程研究所碩士班<br>97<br>In this thesis, design on the slot waveguide structure is to create Y-Branch splitter. The optical field can be enhanced and confine light in a slot-waveguide region of low-index material. Light enhancement and confinement is caused by large discontinuity of the electric field at high-index-contrast interfaces. We use of such a structure the field can be confined in a 50-nm-wide low-index material region, and successfully achieve simulations of 1x2 and 1x4 ultra-small Y-Branch splitters based on silicon-on-insulator ( SOI ). This structure can be used as na
