A lattice model for resonance in open periodic waveguides
Natalia Ptitsyna, Stephen P. Shipman
We present a discrete model of resonant scattering of waves by an open periodic waveguide. The model elucidates a phenomenon common in electromagnetics, in which the interaction of…

Fano-Type Resonance of Waves in Periodic Slabs
Natalia Ptitsyna, Stephen P. Shipman, Stephanos Venakides
We investigate Fano-type anomalous transmission of energy of plane waves across lossless slab scatterers with periodic structure in the presence of non-robust guided modes. Our app…
