Dаtum izdаvаnjа: | сеп-2019 | Izdаvаč: | IEEE | Kоnfеrеnciја: | 13th International Congress on Artificial Materials for Novel Wave Phenomena, Metamaterials 2019 | Sažetak: | The recently emerged concepts of coherent perfect absorption (CPA), i.e., the time-reversed counterpart of a laser and its generalization to Hermitian systems, coherent virtual absorption (CVA), are shown to be ideally suited for all-optical light manipulation. In this work, we demonstrate how the concept of coherent excitation can pave the way to light scattering control in an extreme fashion in non-Hermitian PT-symmetrical systems supporting an embedded eigenstate. | URI: | https://open.uns.ac.rs/handle/123456789/13044 | DOI: | 10.1109/MetaMaterials.2019.8900848 |
