[]The analysis of electromagnetic problems with moving objects has many applications: RF Doppler radars, astrophysics, GPS, electromagnetic gyroscopes… This seminar proposes an original and thorough analysis of the behavior of electromagnetic waves in the presence of moving bodies by using the Finite Difference Time Domain (FDTD) method. Movements are implemented by changing positions of the objects at each time step, through the classical FDTD time loop. With this direct approach, time is implicitly absolute and Voigt-Lorentz transformations are not implemented. This technique is suitable for non-relativistic speeds, thus for most encountered electromagnetic problems, especially in antennas and propagation domain. The numerical aspects that need to be considered are studied. Then, different problems are investigated: moving plane wave source with resistors, moving observation point, moving inclined Partially Reflecting Surface (PRS), moving line source, and moving metallic cylinder illuminated by a plane wave. The results, in terms of Doppler frequency shift and changes in amplitude of the electric field, are compared with those of special relativity which are considered as the references. Some aspects of special relativity are present in the direct FDTD approach, such as the independence of the velocity of electromagnetic wave propagation with the speed of the source and Lorentz local time (with a different physical interpretation). Some of the obtained results agree with special relativity. Other ones are different, but the differences are negligible for non-relativistic speeds. Techniques are proposed for the implementation of relativistic effects. The results obtained with our analysis bring new physical insights on the propagation of waves with moving bodies. In particular, it is shown that the amplitude of the electric field for an ideal plane wave source does not increase with the speed of motion. Moreover, for a moving scattering metallic wire, one can observe a phenomenon similar to shock waves. Other analyzed problems include complexes motions (multiple speeds, acceleration, rotation, oscillation), moving airplanes, Michelson-Morley interferometer, Sagnac effect, Heaviside faster-than-light analysis. Some quantum phenomena (Compton experiment, blackbody radiation) are also studied…Speaker(s): Professor Halim BoutayebAgenda: 11:30pm - 12:15pm: Lecture by Professor Halim Boutayeb12:15pm - 12:30pm: Question and Answer (Q/A)Room: RBCx Finance Quarter, Bldg: Hub350, 350 Legget Dr, Ottawa, Ontario, Canada, K2K 3N1

The presentation highlights the use of interferometric techniques in millimeter wave systems such as high data-rate communication systems, radar sensors or broadband quadrature interferometric mixers. The main advantage of these mixers, compared to conventional ones, are the reduced power requested for the operation. The fabrication technologies used are MHMIC, RW, SIW. All circuits and modules are designed and characterised in our millimeter- wavelaboratory. Fabrication uses outside facilities. As an initial step, computer models based on the VNA measurements are used in computer simulations of the systems to validate the architecture and functionality. This allows important cost reduction on module/transceiver prototypes. Test benches and some measurement results of the fabricated prototypes, from 24 GHz up to 90 GHz are presented and discussed. Future work will include designs at higher frequency, over D-band (110 - 170 GHz), to meet the ongoing requirements of the academia and <a href="http://industry.Speaker(s):" target="_blank" title="industry.Speaker(s):">industry.Speaker(s): Prof. Serioja Ovidiu Tatu, Virtual: https://events.vtools.ieee.org/m/472237

Abstract:This presentation distills the author's heuristics for successfully architecting complex, multi-disciplinary product development projects, characterized by cutting edge technologies and tight schedules. Drawing from the development of MDA's FIRE 9000 Printed Circuit Board Photoplotter product line developed in the 1990s, this talk identifies timeless lessons and best practices that remain relevant today. Attendees will gain valuable insights into project management strategies applicable to contemporary complex product development <a href="http://endeavors.Virtual:" target="_blank" title="endeavors.Virtual:">endeavors.Virtual: https://events.vtools.ieee.org/m/470603
