Linear time-invariant media constitute the foundations of our understanding and applications of electromagnetics, from antenna radiation to wave propagation and scattering. The static nature of time-invariant structures imposes stringent limitations on their properties, and particularly their performance bandwidth, giving rise to fundamental limits such as the Harrington-Chu limit on radiation bandwidth by a small antenna and the Rozanov bound on the bandwidth of a thin perfect absorber. Recently, a new paradigm has been gaining traction, focused on the use of time-modulated elements to overcome these limitations and realize phenomena inaccessible to static electromagnetic systems. In this tutorial lecture, the speaker will provide an overview of the rising field of four-dimensional electromagnetics, elaborating on the new ideas ushered in by combining spatial and temporal degrees of freedom to manipulate electromagnetic waves, envisioning their potential for future applications, and the related challenges and limitations along the way.
Prof. Emanuele Galiffi received his bachelor’s and master’s degrees in physics from Imperial College London in 2016, where he subsequently completed his doctoral studies under the supervision of Prof. Sir John Pendry. For his doctoral research, he was awarded the Johnson Matthey PhD Thesis Prize and a 2020 EPSRC Doctoral Prize Fellowship. He was subsequently awarded a prestigious three-year Junior Fellowship from the Simons Society of Fellows, through which he joined Prof. Andrea Alù’s group at the Advanced Science Research Center of the City University of New York in 2021. He later began a tenure-track appointment at The University of Texas at Austin. His research interests span fundamental and applied electromagnetics and photonics, with a particular focus on metamaterials exhibiting extreme electromagnetic properties, including time-varying, singular, epsilon-near-zero, and highly anisotropic structures. He has co-authored more than 40 peer-reviewed articles in leading journals, including Science, Nature Physics, Nature Photonics, Physical Review X, Physical Review Letters, Nature Communications, and PNAS. His work has received approximately 4,000 citations. For his work on electromagnetic phenomena in time-varying media, he received the 2026 URSI Santimay Basu Award in Radio Science, the 2026 Nanophotonics Early Career Award, and the 2025 SPIE Advanced Photonics Young Innovator Award.

Simulation-driven design changed product development forever, enabling engineers to reduce design, iterations, and prototype testing. Increasing scientific computing power expanded the opportunity to apply analysis, making large design studies possible within the timing constraints of a program. This talk will focus on advanced CEM simulation tools that incorporate numerical methods, such as Method of Moments (MoM), Multilevel Fast Multipole Method (MLFMM), Finite Element Method (FEM), Finite Difference Time Domain (FDTD), Physical Optics (PO), Ray Lunching Geometrical Optics (RL-GO), and Uniform Theory of Diffraction (UTD). As the complexity of connected devices increases each day, designers are taking advantage of AI/ML to generate trained models for their physical antenna designs and perform fast and intelligent optimization on these trained models. Using the trained models, different optimization algorithms and goals can be run quickly, in seconds, that can be utilized for comparison studies, stochastic analysis for tolerance studies etc. Use of cloud computing combined with AI/ML, many design iterations can be performed in a short period and reducing the time to market. This talk will also focus on future trends in cloud computing for physics-based simulations and the emerging topics such as Digital Twins.
