Abstract: In this talk, we will discuss two recent observations from our group that have challenged widespread assumptions held (by us included!) about the optical response of commonly used optical materials: that material polarization can safely be considered to respond locally to the electric field and that the second-order nonlinear response of amorphous films should vanish due to centrosymmetry. In the first part of the talk, we will describe our proposal for a new type of optical antenna dubbed a “photonic gap antenna”, and our realization of its extreme version using an epsilon-near-zero (ENZ) material. Such antennas can provide electric field enhancements of >100 and large Purcell factors without requiring stringent nanofabrication. To our surprise, when measuring third harmonic generation as a proxy for field enhancement, sharp peaks emerge in the response that are completely absent in our full wave electromagnetic calculations. We find that the appearance of these peaks can only be explained when including nonlocality in the dielectric response of the ENZ material. Nonlocal simulations show that the volume averaged field enhancement can be 4–6 greater than that predicted by the local model, which becomes an important consideration when designing optical devices. In the second part of the talk, we will describe our recent discovery that amorphous thermally evaporated organic thin films of small molecules can have second-order optical nonlinearities on par with those of state-of-the-art nonlinear materials (c(2)31, c(2)33 >50 pm/V), with the important advantage that they can be deposited on arbitrary photonic platforms. We will show that by harnessing the interplay between dipole-dipole interactions and surface energy minimization, it is possible to spontaneously break centrosymmetry during thermal evaporation, without the need for special alignment procedures. In addition to its applications in photonics, this observation has allowed us to better understand molecular alignment beyond the mean molecular orientation <a href="http://angle..Co-sponsored" target="_blank" title="angle..Co-sponsored">angle..Co-sponsored by: Prof. Nicolas QuesadaSpeaker(s): Stéphane Kéna-CohenJ.

Global and Regional politics are also creating new, more demanding and often contradictory demands on new grads, while at the same time increasingly destabilizing the year to year demand for new engineering employees. Generally, despite growing demands for employees, many engineers now in the universities are having difficulty obtaining meaningful summer and co-op term employment opportunities, and as a result get less out of their classes and have further difficulties finding permanent positions on graduation. Even if they find a position it is increasingly difficult for them to assess potential career options as the driving forces for projects and economics are highly variable due to political and societal changes that may or may not result in long term opportunities. This presentation will take a high-level look at how employment outlooks have changed for specific cases of Petroleum Engineering roles and how the working environment has been more chaotic for Chemical Engineering design roles for industrial positions when success criteria and design criteria are being influenced by often illogical or unsupported external influences. This changing world can greatly influence career choices for grads and potentially lead them down blind alleys from which they may or may not emerge from as professionals. This will be contrasted to the presenter’s own career progression since his 1976 <a href="http://graduation.Bio:" target="_blank" title="graduation.Bio:">graduation.Bio: Bruce Peachey, BScChE (U of S ‘76), P.Eng. is President of New Paradigm Engineering Ltd. and has over 45 years of experience in the Canadian oil and gas industry.

The development of interconnected DC transmission grids requires significant further advance from the existing point-to-point HVDC links. It is widely believed that complex DC power grids can be built with comparable performance, reliability, flexibility and losses as traditional AC grids. The primary motivation for DC grid development is the need for power flow and trading between many DC terminals, as an example in the proposed (350 GW) North Sea DC grid, or EU-wide overlay DC grid. AC transmission is not feasible with long subsea cables, and it is inferior to DC systems in many other conditions. This presentation addresses the options and challenges with DC grid development, referring also to state-of-art technology <a href="http://status.Zhangbei" target="_blank" title="status.Zhangbei">status.Zhangbei 4-terminal DC system (China, 2020) represents the first implemented GW-scale meshed DC transmission grid, which employs bipolar ring topology with overhead lines and 16 DC Circuit Breakers. However, multiple studies illustrate advantages of some radial, hub-based or segmented topologies, because of component costs, and challenges with interoperability, ownership, DC markets, operation, security and <a href="http://reliability.MMC" target="_blank" title="reliability.MMC">reliability.MMC concepts, including half-bridge and full-bridge modules, will underpin DC grid converters and further advances like hybrid LCC/MMC converters have been implemented recently. DC/DC converters at hundreds of MW are not yet commercially available but there is lot of research world-wide, and some lower-power prototypes have been demonstrated. DC/DC converters may take multiple functions including: DC voltage stepping (transformer role), DC fault interruption (DC CB role) and power flow control. Multiport DC hubs can be viewed as electronic DC substations, capable of interconnecting multiple DC <a href="http://lines.Very" target="_blank" title="lines.Very">lines.Very fast DC CB circuit breakers (2 ms) have become commercially available recently, but the cost is considerably higher than AC CBs. Slightly slower mechanical DC CBs (5-8 ms) are also available from multiple vendors, while new technical solutions are emerging worldwide for achieving faster operation with lower size/weight/<a href="http://costs.DC" target="_blank" title="costs.DC">costs.DC grid modelling will face the new challenge of numerous converters dynamically coupled through low-impedance DC cables/lines. A compromise between simulation speed and accuracy is required, leading to some average-value modelling, commonly in rotating DQ frame, but capturing very fast dynamics and variable structure to represent fault <a href="http://conditions.The" target="_blank" title="conditions.The">conditions.The principles of control of DC grids have been developed. DC systems have no system-wide common frequency to indicate power unbalance, and voltage responds to local and global loading rather than reactive power flow. DC grid dynamics are 2 orders of magnitude faster than traditional AC systems and most components will be controllable implying numerous, fast control loop interactions. Because of lack of inertia, and minimal overload capability for semiconductors, DC grid primary and secondary control should be feedback-based (man-made), fast, and distributed. International standardisation efforts have <a href="http://begun.The" target="_blank" title="begun.The">begun.The protection of DC grids is a significant technical challenge, both in terms of components and protection logic. The selectivity has been demonstrated within 0.5 ms timeframe using commercial and open-source DC relays. Nevertheless, grid operators have expressed concerns with self-protection on various components, back-up grid-wide protection, interoperability, and in general if we can achieve power transfer security levels comparable with AC grids and acceptable to <a href="http://stakeholders.Bldg:" target="_blank" title="stakeholders.Bldg:">stakeholders.Bldg: Donadeo Innovation Centre For Engineering (ICE), Fred Pheasy Engineering Commons (8-292), 9211 116 St NW, Edmonton, Alberta, Canada, T6G 1H9
