Abstract

Read online

Perfect absorption can be obtained for a single port device, or a device with multiple incident beams, but for multiport devices, the absorption is limited to around 50%. In this work, Rao et al. overcome this limitation, demonstrating near perfect absorption in a two port cavity magnon system.
