This talk presents wave-based sensing and fast modeling methods spanning time-reversal acoustics, nonlinear piezoelectric tuning, and magneto-acoustic device physics. I describe a time-reversal acoustics (TRA) measurement system for detecting change events in complex environments where optical line-of-sight is blocked. The system detected both gross changes (e.g., removing an object from a dense “forest” of posts) and subtle tampering (e.g., material substitution), with sub-wavelength spatial sensitivity. Simulation tools revealed object and boundary interactions encoded in the time signals and quantified the impact of sensor geometry and boundary conditions on detection and localization. Second, we developed simulation capability to predict tuning in nonlinear RF devices, demonstrated voltage-controlled frequency tuning in X-cut lithium niobate (LN) on insulator, and created tools for nonlinear coupling analysis. A key outcome is capturing nonlinear effects with effective-medium properties, enabling applications such as real-time RF device temperature stabilization. Third, I motivate acoustically driven ferromagnetic resonance (ADFMR) for energy-efficient control of magnonic devices via magnetoelastic coupling driven by piezoelectric transducers. Lastly, I describe fast simulation approaches for magneto-acoustic devices using perturbation theory and a Stroh-formalism framework for efficient modeling of magnetoelastic layered media.

As vegetation remains a leading ignition risk, utilities are reimagining programs through technology. Learn from Adam Pahls, Senior Manager at the Wilfire Mitigation Department of Evergy Inc. on how lidar mapping, predictive growth models, and risk-based trimming cycles are helping utilities optimize budgets, extend maintenance intervals, and deliver measurable reductions in fire potential. Refreshments will be provided at the event. Speaker(s): Adam Room: 233, Bldg: Rhatigan Student Center, Wichita State University, Wichita, Kansas, United States
