In-situ Time-domain Physical Adjoint Optimization of Complex Wave Dynamics
Hoyeong Kwon, Arunn Suntharalingam, Laureano Bulus-Rossini +1
Direct optimization of complex wave dynamics through the intrinsic evolution of physical systems is fundamentally limited by the lack of directly accessible gradients. Adjoint meth…
In-situ adjoint protocols for nonlinear PT-symmetric self-optimizing machines
Zheming Li, Lucas J. Fernández-Alcázar, Zin Lin +1
Adjoint methods provide a powerful route for gradient-based optimization, but their physical implementation is obstructed in generic nonlinear systems because the adjoint dynamics…
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…
