Wavefront shaping simulations with augmented partial factorization
Ho-Chun Lin, Zeyu Wang, Chia Wei Hsu
Wavefront shaping can tailor multipath interference to control multiple scattering of waves in complex optical systems. However, full-wave simulations that capture multiple scatter…
Full transmission of vectorial waves through 3D multiple-scattering media
Ho-Chun Lin, Chia Wei Hsu
A striking prediction from the random matrix theory in mesoscopic physics is the existence of "open channels": waves that can use multipath interference to achieve perfect transmis…
Correlation-enhanced control of wave focusing in disordered media
Chia Wei Hsu, Seng Fatt Liew, Arthur Goetschy +2
A fundamental challenge in physics is controlling the propagation of waves in disordered media despite strong scattering from inhomogeneities. Spatial light modulators enable one t…
Perfect Single-Sided Radiation and Absorption without Mirrors
Hengyun Zhou, Bo Zhen, Chia Wei Hsu +4
Highly directional radiation from photonic structures is important for many applications, including high power photonic crystal surface emitting lasers, grating couplers, and light…
Topological nature of bound states in the radiation continuum
Bo Zhen, Chia Wei Hsu, Ling Lu +2
Bound states in the continuum (BICs) are unusual solutions of wave equations describing light or matter: they are discrete and spatially bounded, but exist at the same energy as a…
