Abstract: The following presentation demonstrates the role of Computational Electromagnetic (CEM) in consumer electronics design, specifically AR/VR. Simulation of these devices during the initial exploration stages is crucial to understanding the pros and cons of antenna locations and their proximity to various sub-systems. The desired polarization and radiation patterns envelope are key deciding parameters, along with S11 and isolation. Hence, these simulated data with and without human phantom are beneficial for architecture reviews when the prototype and field data are unavailable and (or) hard to collect. This presentation demonstrates the role of virtual human phantoms and the various challenges affecting antenna performance based on antenna placement, body positioning, multi-antenna coupling, and operating environment in the Wi-Fi frequency band. We also highlight the process of obtaining accurate and efficient simulation results by leveraging SIMULIA CST Studio Suite technology for AR/VR simulation needs.
Biography: Prathap Valale PRASANNAKUMAR is an antenna engineer in the Reality Labs at Meta Platforms, Inc. He has worked on Oculus Quest 2 VR devices. His current research is focused on Wi-Fi (2.4 GHz, 5 GHz, and 6 GHz), Bluetooth, and UWB antennas and improving the isolation between collocated antennas in AR/VR consumer electronics devices. His Ph.D. thesis focuses on the design of monostatic, quasi-monostatic, and bistatic simultaneous transmit and receive (STAR) or In-Band Full-Duplex (IBFD) antenna systems and wideband isolation enhancement techniques. He has over 7.5 years of experience in numerical EM simulations – Method of Moments (MoM), Finite Element (FEM), Time-domain (FIT), hybrid solvers, and other 2D and 2.5D solvers. Dr. Prathap received his MS and Ph.D. degrees in electrical engineering from the University of Colorado, Boulder. Previously he has worked as a deputy engineer in Bharat Electronics, India. Dr. Prasannakumar is also one of our 2022 SIMULIA Champions.
