Title of Speech: Design of Metamaterials using Transformation Physics
Abstract: Metamaterials are rationally designed artificial materials composed of tailored functional building blocks densely packed into an effective (crystalline) material. While metamaterials historically are primarily thought to be associated with negative refractive indices and invisibility cloaking in electromagnetism or optics, it turns out that the simple metamaterial concept also applies to many other areas of physics namely the thermodynamics, classical mechanics (including elastostatics, acoustics, fluid dynamics and elastodynamics) and in principle also to the quantum mechanics. This lecture will review the basic concepts and analogies behind the thermodynamic, acoustic, elastodynamic/elastostatic, and electromagnetic metamaterials and differences among them. It will provide an overview of the theory, the current state of the art and example applications of various types of metamaterials. The review will also discuss the homogeneous as well as inhomogeneous metamaterial architectures designed by coordinate-transformation-based approaches analogous to transformation optics. The application examples will include laminates, thermal cloaks, thermal concentrators and inverters, anisotropic acoustic metamaterials, acoustic free-space and carpet cloaks, and mechanical metamaterials with negative dynamic mass density, negative dynamic bulk modulus, or negative phase velocity. Finally an example of quantum-mechanical matter-wave cloaking will be provided.

Title of Speech: High Performance Micro Electro Mechanical Systems (MEMS) Actuators and Sensors
Abstract: Many emerging applications in adaptive optics, positioning lenses for auto focusing/zooming in cameras, micromanipulators, sensing for autonomous vehicles and vector display for HUD in automotive systems and many others require the manipulation of masses with milligrams in size and the generation of out-of-plane displacement ranging from few to hundreds of micrometers. This is difficult to achieve at the microscale. The talk will be presenting novel MEMS actuator platforms that provide out-of-plane motion leading to a stroke that is orders of magnitude higher than standard micro actuators and the generating of large forces. Different implementations of these micro-actuators are shown and their use for developing a number of applications including 3D micromirrors for vector display and automotive head up display, and autofocus and optical Image stabilization in phone cameras. The same MEMS platform is shown to provide for very high sensitivity and very large range sensing capability and is shown through implementations as micro accelerometers and micro force sensors for high performance applications.

Title of Speech: Cyber Physical Systems Role in Manufacturing and Factory Automation
Abstract: Empowered by the recent development in single system-on-chip, internet of things and cloud computing technologies, cyber physical systems are evolving as a major player during and post manufacturing product process. In additional to its real physical space, products have nowadays a virtual space. A product virtual space is a digital twin that is attached to it to enable manufacturers and their clients to better manufacture, monitor and operate a product during their life time cycles i.e. from the product manufacturing, through operation and to recycling. Each product is equipped with a tiny microcontroller and has a unique WiFi address that allows accessing it anytime and anywhere during its life cycle. This talk will highlight the industry 4.0, role of internet of things and cloud computing in industrial manufacturing and factory automation.

Title of Speech: Novel Nitride-based Quantum-wells and Superlattices
Abstract: Novel dilute III-V nitride based quantum-wells (QWs) and superlattices (SLs) have recently gained considerable attention among the academic and engineering community. The materials exhibit unusual and fascinating physical properties with a strong band-gap energy bowing effect that allow widely extended band structure engineering applications ranging from telecom lasers to high efficient solar cells. The high interest has also been driven by the potential technological advantages provided by the novel dilute III-V nitrides in lattice matching to GaAs and Si substrates. Currently there is a high demand of the low cost, high performance long wavelength (1.3-1.6 mm) vertical cavity surface-emitting lasers (LW- VCSEL) for the use in the rapid expansion of optical metro area networks. Intensive research efforts on LW-VCSELs have yielded significant results in terms of higher differential efficiency, lower current thresholds, higher operating temperature and high-speed modulation bringing such devices closer to commercial reality. Recent work on GaAs-based lasers with a small amount of nitrogen (dilute III-V-N based materials) has taken advantage of the well-developed GaAs processing techniques and the superior DBR mirror-technology available for the VCSEL operation in the desired long wavelength range. Adding a small amount of N (<5%) to GaAs alloys preserve the direct band gap (has a type-I band offset) and bows the band gap to much lower energies while shrinking the lattice constant. Adding N to GaInAs pushes emission to longer wavelengths and offsets the In lattice mismatch, making higher In concentrations possible. Despite the impressive technological developments and the realization of high efficient solar cells, edge emitting lasers and VCSELs in the 1.1- 1.3 mm wavelength range, many fundamental issues in III-V-N materials have still remain unresolved for producing useful the threshold current density are currently the major challenges. Difficulties still persist in obtaining good quality alloys and the devices still exhibit a high threshold current density. Challenges remain in the understanding of growth and materials’ unusual properties. This work is intended to review the progress made in the growth and characterization of the novel III-V-N based LW-laser material structures. Here we report the results of our recent efforts made both theoretically and experimentally to understand the fundamental material issues related primarily to (i) the N incorporation resulting non-radiative defects; (ii) the limitation on the maximum attainable free-electron and/or hole concentration by doping; (iii) understanding of the formation of intrinsic point- and/or extended-defects and their interaction with the dopants either during epitaxial growth or with the incorporated H in III-V-Ns; (iv) the microscopic nature of N-H complexes responsible for the unusual bandgap increase in hydrogenated III-V-Ns; and (v) accurate knowledge of the dielectric functions and mechanism responsible for the unusual electronic and optical properties of III-V-Ns (e.g., the influence of N and/or disorder), QWs (e.g., the band-edge alignment; inter-diffusion effects, etc.) and SLs.
