Speech Title: Predictive Manufacturing: Subtractive and Additive
Abstract: Manufacturing is the key to today’s industrial competitiveness, and it is broadly classified into two categories, subtractive and additive. In current study, the ability to predictively model manufacturing performance attributes in both categories is introduced. In subtractive manufacturing, modeling of laser-assisted and ultrasonic vibration-assisted milling are presented. In laser-assisted milling, the laser preheating temperature field is predicted, and the dynamic recrystallization as well as grain growth triggered under high temperature is considered, which enhances the accuracy of force and residual stress prediction. In ultrasonic vibration-assisted milling, the intermittent effect is considered through tool-workpiece separation criteria. And the force reduction in ultrasonic vibration-assisted milling is accurately predicted. In additive manufacturing, laser-assisted metal additive manufacturing is introduced. And the predictive modeling of temperature field in powder bed metal additive manufacturing is presented. The model considers heat transfer boundary including heat loss from convection and radiation at the part boundary. Through the comparison between measured and calculated molten pool dimensions, the model is proven to have high computational efficiency and high prediction accuracy.

Speech Title: Design of Metamaterials with Unusual Properties 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, hydrodynamic 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.

Speech Title: 3D-Printed mm-Wave Devices and Circuits for System-in-a-Package Applications
Abstract: This invited talk will present
our recent research towards strategic design, additive manufacturing (AM
also known as 3D printing), and characterization of devices, interconnects
and circuits for the emerging mm-Wave and sub-THz system-in-a-package (SiP)
applications. This talk begins with a brief overview of our research
activities for development of a diverse library of well-characterized
functional materials suited for additive manufacturing of mm-W devices,
interconnection and packaging of integrated circuits (MMIC’s). The newly
developed feedstock composites exhibit promising EM properties (er=4~12 and
tandd <0.002) well suited for applications ranging from RF to mmW
frequencies (with tested properties up to 110 GHz).
The 3D printed transmission lines and probe pads can be re-rendered to reach µm scale accuracy by laser trimming to facilitate on-package probe testing. The frequency response of a custom-designed distributed amplifier with a fully 3D printed chip assembly have been characterized between 1 GHz and 30 GHz, which exhibit much better wideband performance than an identical QFN-packaged amplifier. On-package probe measurements of a 3D printed microstrip line has exhibited low insertion losses of 0.028 dB/mm at 5 GHz and 0.187dB/mm at 20 GHz, while CPW lines show an insertion loss lower than 0.34 dB/mm at 110 GHz.
This talk also presents a comprehensive study of the design of a multilayer dielectric rod waveguide (DRW), which is comprised of a high permittivity core encased by a low permittivity cladding. The insertion loss of the multi-layer DRW is less than 0.012 dB/mm at Ku-band frequencies and as low as 0.4 dB/mm at WR6 band (110-170 GHz). A dielectric rod antenna (DRA) that consists of a medium permittivity dielectric rod core encased by a low permittivity cladding is also designed to raise the peak gain by 3-9 dB at 30-40 GHz.
