Texte intégralIn a broad sense, the term wave localization refers to a phenomenon where waves are spatially confined in small regions of the space without any bounding material barriers.In this Thesis, we investigate (analytically, numerically and experimentally) different physical collective mechanisms to spatially localize, and therefore, to control electromagnetic waves. Specifically, we focus on the role of uncorrelated and correlated potentials, as well as of topological effects to achieve wave confinement. Analytical and numerical studies are accomplished in the framework of a recent approach in the modeling of Anderson localization called localization landscape theory. On the other hand, experiments are performed using a microwave platform composed by small dielectric cylinders placed inside a cavity made of two metallic plates. The cavity implements a propagative wave system, where we can efficiently control the local permittivity by means of the cylinders acting as scatterers, or as an analogic tight-binding system, where, in this case, the dielectric cylinders play the role of resonators.First, we extend the scope of the localization landscape approach to a wide class of one and two dimensional tight-binding systems in the presence of uncorrelated disorder, where localized eigenfunctions appear in both band-edges. We demonstrate how the landscape theory is able to predict accurately not only the locations, but also the energies of localized eigenfunctions in the low- and high-energy regimes. Later, by using our experimental cavity as a propagative system, we perform microwave transport experiments in two dimensional planar arrays. Experiments are carried out on a disordered lattice and on an aperiodic Vogel spiral from where we characterize the electromagnetic modal structures in real space. Our results reveals that aperiodic systems can carry a rich variety of long-lived modes—with Gaussian, exponential, and power law spatial decays—which are able to survive even in a three-dimensional environment. This is supported by different transport quantities such as the density of states, the characteristic decay time, and the Thouless conductance that are also experimentally accessible. On the contrary, we show that the eigenstates in traditional disordered media are always limited to exponential radial decays with leaking features beyond two-dimensions.Finally, we use the experimental tight-binding configuration to investigate the propagation of topological helical states. Particularly, we experimentally analyze a set of honeycomb-like structures built using a triangular lattice with an hexagonal unit cell, which are characterized by the Z_2 topological invariant. By recovering the modal structure in real space and the density of states, our results reveal the possibility to open a topological gap, dwelt by edge states that lives in the border of the structure.We demonstrate the unidirectional counterpropagative features of such helical edge states.Taken together, our results demonstrate that it is possible to model, control and localize electromagnetic waves not only within, but beyond Anderson's conception. Thanks to the crossroads we have taken, we have mapped out an itinerary that brings us closer to the main avenue leading perhaps to Anderson localization of three dimensional electromagnetic waves

Face milling is a popular cutting method in mass production of spiral bevel gears. A CNC machine with five-axis simultaneous control system is demanded to implement face milling. This cutting method needs multi-axis movement and its tool design is complex. Therefore, in order to avoid collision, the simulation of tool paths and material removal should be performed previously to verify the correctness of NC codes. The study aims to develop a dedicated cutting simulation software for face-milled spiral bevel gears. Visual C# 2010 integrated with OpenGL is used as a foundation to develop the simulation program. Here, a voxel method for cutting simulation is employed. The mathematical model of tool surface is first established. The solid model of work gear is composed by cubes in which voxels are used to store the positions and values of those vertexes. According to the NC code, the relative positions between the tool and the work gear are determined through the coordinate transformations. And then, Boolean difference operation between the gear work and tool is made to simulate gear cutting. Moreover, the marching cube algorithm is adopted to improve the display resolution of produced tooth surfaces which are save as STL (Stereolithography) format. In order to verify the correctness of NC codes, an evaluation method is proposed to obtain tooth surface deviations between the produced STL surfaces and theoretical surfaces. And, the volume removal is obtained in real-time cutting simulation, which can be used as a beneficial data for further reach in optimization of NC tool paths.
