In-situ Adjoint Wave Control in Reconfigurable Non-Hermitian Nonlinear Systems
John Guillamon, William Tuxbury, Cheng-Zhen Wang +3
Complex multipath environments are usually avoided in wave-based information processing because repeated scattering creates many interfering propagation paths, obscuring controllab…
Brewster-anomaly delocalization for free-electron radiation
Zheng Gong, Xiangfeng Xi, Hongsheng Chen +3
Localization effects are central to disordered electronics and photonics. In electronics, Anderson localization governs electron confinement in randomly perturbed lattices. Similar…
Dispersion Engineered Metastructures Enabling Broadband Angular Selectivity
Phillippe Pearson, Zhaowei Dai, Yiran Gu +2
Angle-selective optical devices are of importance to several applications such as photovoltaics, high-sensitivity photodetectors and displays. There are several approaches to reali…
Coherent Control of Wave Scattering via Minimal-Parameter Tuning of Complex Spectra
Ali H. Alhulaymi, Nazar Pyvovar, Philipp del Hougne +2
We introduce and validate a theoretical framework for coherent control of multichannel linear scattering to route waves through complex geometries with multiple scattering. We show…
