Physical Violations of the Bulk-Edge Correspondence in Topological Electromagnetics
S. Ali Hassani Gangaraj, Francesco Monticone
In this Letter, we discuss two general classes of apparent violations of the bulk-edge correspondence principle for uniform topological photonic materials, associated with the asym…
Can a nonradiating mode be externally excited? Nonscattering states vs. embedded eigenstates
Francesco Monticone, Dimitrios Sounas, Alex Krasnok +1
In this Letter, we discuss the general problem of exciting radiationless field distributions in open cavities, with the goal of clarifying recent findings on this topic. We point o…
Anomalies in Light Scattering
Alex Krasnok, Denis Baranov, Huanan Li +3
Scattering of electromagnetic waves lies at the heart of most experimental techniques over nearly the entire electromagnetic spectrum, ranging from radio waves to optics and X-rays…
Do Truly Unidirectional Surface Plasmon-Polaritons Exist?
S. Ali Hassani Gangaraj, Francesco Monticone
In this work, we revisit the topic of surface waves on nonreciprocal plasmonic structures, and clarify whether strictly unidirectional surface plasmon-polaritons are allowed to exi…
Robust surface plasmon polaritons on gyrotropic interfaces
Samaneh Pakniyat, Alexander M. Holmes, George W. Hanson +5
Unidirectional surface plasmon polaritons (SPPs) at the interface between a gyrotropic medium and a simple medium are studied in a newly-recognized frequency regime wherein the SPP…
