A Lossless Sink Based on Complex Frequency Excitations
Abstract The creation of a sink in a lossless wave‐bearing medium is achieved using complex frequency signals—harmonic excitations that exponentially grow in time. The wave sink, where incident waves are confined to a point, has attracted interest for imaging and sensing since it may lead to arbitra...
