Controlling coherent perfect absorption via long-range connectivity of defects in three-dimensional zero-index media
Coherent perfect absorption (CPA), as time-reversed lasing, arises from appropriate wave interference within absorbers, offering flexible control over wave absorption. Typically, this control involves tuning the phase difference between two counter-propagating incident beams. Here, we elucidate the...
