Joint control of coherent transmission, reflection, and absorption
Shiyu Li, Dongha Kim, Shanhui Fan +1
Controlling multiple wave properties simultaneously poses a key challenge in coherent control of wave transport. We present a theory for joint coherent control of transmission, ref…

Generating topological non-diffracting beams using high quality factor nonlocal metasurfaces
Dongha Kim, Charles Pelzman, Cheng Guo +3
Non-diffracting optical beams are essential tools in photonics, enabling robust light transport, super-resolution imaging, and spatiotemporal control. While nonlocal metasurfaces h…
