The local symmetries of the medium are shown to yield piecewise translation-invariant quantities, which are used to distinguish resonances with arbitrary field profile from resonances following the medium symmetries. Focusing on light scattering in aperiodic multilayer structures, we demonstrate this classification for representative setups, providing insight into the origin of perfect transmission. We further show how local symmetries can be utilized for the design of optical devices with perfect transmission at prescribed energies. Providing a link between resonant scattering and local symmetries of the underlying medium, the proposed approach may contribute to the understanding of optical response in complex systems. 9 pp. LOMv1.0 creator LOMv1.0 publisher LOMv1.0 Scientific Coordinator LOMv1.0 Project Executing Organisation 2013-09-30 Digital Library of the Operational Programme "Education and Lifelong Learning" abstract types Text Perfect transmission Transmission properties One-dimensional optical media Local symmetries Aperiodic systems Photonic multilayered devices http://journals.aps.org/pra/abstract/10.1103/PhysRevA.88.033857 425816 application/pdf http://repository.edulll.gr/edulll/bitstream/10795/2910/2/2910_1.91_%ce%94%ce%97%ce%9c_30_9_13.pdf URI http://hdl.handle.net/10795/2910 LOMv1.0creator 2016-04-26T08:07:08Z LOMv1.0validator 2016-04-26T08:07:08Z LOMv1.0 gre no no Copyright EYD-EPEDBM (Operational Programme "Education and Lifelong Learning")
