On-off switchable nonreciprocal negative refraction in non-Hermitian photon-magnon hybrid systems
Junyoung Kim, Bosung Kim, Bo-Jong Kim +2
Photon-magnon coupling, where electromagnetic waves interact with spin waves, and negative refraction, which bends the direction of electromagnetic waves unnaturally, constitute cr…

Non-reciprocal absorption and zero reflection in physically separated dual photonic resonators by traveling-wave-induced indirect coupling
Bojong Kim, Junyoung Kim, Hae-Chan Jeon +1
We experimentally explored novel behaviors of non-reciprocal absorption and almost zero reflection in a dual photon resonator system, which is physically separated and composed of…
