Dr. Arthur D. Yaghjian (Electromagnetics Research) Robust Field-Based Antenna Quality Factor Abstract – New field-based quality factors Q(ω) are derived for antennas with known fields produced by an input current. These Q(ω) are remarkably robust because they equal the input-impedance bandwidth quality factor QZ(ω) when the input impedance is available. Like QZ(ω), the field-based Q(ω)

Armando Genco (Politecnico di Milano) Ultrafast dynamics of coherent exciton-polaritons in van der Waals semiconductor metasurfaces Abstract - Metasurfaces based on transition metal dichalcogenides (TMDs) have emerged as a promising platform for controlling light at the nanoscale due to their exceptional optical properties, including strong excitonic responses and intrinsically high refractive index. Unlike traditional dielectric metasurfaces,

Dr. Marc Serra Garcia (AMOLF) Physical computing in metamaterials Abstract - There is a significant range of physical phenomena—from nonlinear elasticity, to symmetry, noise, topology, and disorder — that are rarely utilized in traditional computing paradigms. Yet these phenomena can unlock new efficiencies, by directly processing signals in their natural domain, and by bypassing the

Dr. Jacob Khurgin (Johns Hopkins University) Coherent Frequency Combs in Mid-Infrared and THz Produced By Self Frequency Modulated Quantum Cascade Lasers For many applications Optical Frequency Combs (OFCs) require a high degree of temporal coherence and thus narrow linewidth1 as well as wide bandwidth (i.e. many spectral lines.  Commonly OFCs are generated in some nonlinear

Dr. Giuseppe Strangi (Case Western Reserve University) Thin-Film Photonics: Enabling Fano Resonances and Optomechanics Abstract – In recent years, significant interest has emerged in the inverse design1 of artificial layered heterostructures for photonic applications2. Specifically, the unique optical properties of near-zero permittivity (ENZ) metamaterials have enabled the exploration of novel physical effects and mechanisms. In

Dr. Mikhail Belkin, Technical University of Munich (TUM) New Applications for Nonlinear Intersubband Polaritonic Metasurfaces: from beam shaping to THz generation Abstract - Quantum-engineered intersubband transitions in n-doped multiple-quantum-well heterostructures allow one to produce semiconductor films with very large nonlinear optical response. This nonlinear response can be further enhanced by processing semiconductor heterostructures as metasurfaces

Publishing in Nature Journals workshop. Day 1 (January 23rd) 10am-11:30am - Seminar on writing, science publishing and editorial decision making Understanding the role of editorial evaluation is crucial, especially in today's dynamic landscape where diversity is ever-present yet often overlooked. This talk will explore the three key stages of research and publishing: effectively identifying current

Dr. Giovanni Milione NEC Laboratories America, Inc. Vector Beams and Space Division Multiplexing Abstract – In this talk, I will overview two areas of my research at NEC Laboratories America, Inc.: For plane wave solutions to Maxwell’s equations, light’s polarization is understood. Not so for structured light. In this talk I’ll discuss non-trivial higher-order solutions

Simo Pajovic Department of Mechanical Engineering, Massachusetts Institute of Technology Controlling Light-Matter Interactions in Novel Emitters: Thermal Radiation, Scintillation, and Beyond Abstract - In mechanical engineering, thermal radiation is the best-known example of light-matter interactions, but non-thermal radiation is prevalent in a wide variety of applications, including medical imaging, manufacturing, and sensing. Scintillation—the emission of light

Dr. Levent Sevgi IEEE AP-S Former DL – DLPC Chair ITU - Istanbul Technical University (Emeritus) From Engineering Elecromagnetics to Electromagnetic Engineering:Teaching/Training Next Generations Abstract - The role of Electromagnetic (EM) fields in our lives has been increasing.

Dr. Mu Wang National Laboratory of Solid State Microstructures, School of Physics, and Collaborative Innovation Center of Advanced Microstructures, Nanjing University, Nanjing 210093, China Manipulating Light with Optical Metasurfaces: from Classical to Quantum Abstract - This talk focuses on the interaction of electromagnetic waves with metamaterials and manipulating the polarization state of light, which are

Nonlinear Photonics in the Mid-Infrared and Terahertz Abstract – Optical sensing at long wavelengths presents significant opportunities and significant challenges. The longwave infrared and terahertz ranges are renowned for their potential to sense molecules in a variety of contexts, such as high-speed chemical imaging, disease detection, and environmental monitoring; however, their promise has yet to

Multi-Beam Antennas (MBAs) and Beam-Forming Networks (BFNs) Abstract - Distinguished Speakers Giovanni Toso and Piero Angeletti from European Space Agency, Netherlands will present the state of the art and the on-going development in Multi-Beam Antennas (MBAs) and Beam-Forming Networks (BFNs). They find applications in several fields including communications, remote sensing (e.g. radars, radiometers, etc.), electric surveillance

Exact formulation of the mutual particle-cavity dynamics and its use for the study of loss threshold phenomenon under magnetization Abstract – Light-matter interaction plays a pivotal role in pushing forward nanotechnology. A particularly important setup involves a resonating particle, say an emitting molecule or a macroscopic quasi-statically resonating plasmonic or ferromagnetic sphere, that is located

Non-Abelian Braiding with Sound and Light Abstract – Many physics laws and mathematical rules are insensitive to order. For example, the addition of numbers disregards the sequence order, e.g., 1+2+3=3+1+2. However, such a commutative property does not always hold. When the outcomes of a set of operations depend on the execution order, they can become

Light-Matter Interactions at the Nanoscale: Harmonic Generation from Metal/Vacuum Interfaces and Novel Aspects of Radiation Reaction Abstract – In noble metals a patina of free electrons extends out into free space and vanishes within a fraction of an atomic diameter. We discuss the possibility and consequences of the existence of such a free electron layer,
