Multi-Objective Tweezers in Scattering Media
Tristan Nerson, Jakob Hüpfl, Clément Ferise +5
Radiation forces and torques enable the manipulation of objects with acoustic and electromagnetic waves. Yet, harnessing them in complex scattering media remains a formidable chall…
Exceptional Points, Lasing, and Coherent Perfect Absorption in Floquet Scattering Systems
David Globosits, Puneet Garg, Jakob Hüpfl +4
Periodically time-varying media, known as photonic time crystals (PTCs), provide a promising platform for observing unconventional wave phenomena. We analyze the scattering of elec…
Resonant states of structured photonic time crystals
Adrià Canós Valero, Sergei Gladyshev, David Globosits +3
Photonic time crystals (PTCs) are spatially uniform media with periodic modulation in time, enabling momentum bandgaps and the parametric amplification of light. While their potent…
Detecting and Focusing on a Nonlinear Target in a Complex Medium
Antton Goïcoechea, Jakob Hüpfl, Stefan Rotter +2
Wavefront shaping techniques allow waves to be focused on a diffraction-limited target deep inside disordered media. To identify the target position, a guidestar is required that t…
Inverse design of mirror-symmetric disordered systems for broadband perfect transmission
Zhazira Zhumabay, Clément Ferise, Vincent Pagneux +2
We present a framework for achieving broadband perfect wave transmission in complex systems by optimizing symmetric disordered media via inverse design. We show that leveraging sym…
T-matrix representation of optical scattering response: Suggestion for a data format
Nigar Asadova, Karim Achouri, Kristian Arjas +39
The transition matrix, frequently abbreviated as T-matrix, contains the complete information in a linear approximation of how a spatially localized object scatters an incident fiel…
