Breaking transmission symmetry without breaking reciprocity in linear all-dielectric polarization-preserving metagratings
S. Foteinopoulou
Transmission asymmetry in reciprocal systems offers an appealing alternative to bulkier non-reciprocal implementations for certain applications. Common reciprocal routes to transmi…
Compact photonic-crystal superabsorbers from strongly absorbing media
G. C. R. Devarapu, S. Foteinopoulou
We present a route to near-perfect absorption in compact photonic-crystal (PC) structures constructed from strongly absorbing media that are typically highly reflective in bulk for…
Extended slow-light field enhancement in positive/negative-index heterostructures
S. Foteinopoulou, J. P. Vigneron
We present a bi-waveguide paradigm composed of joined Positive-Index-Material PIM)/Negative-Index-Material (NIM) slabs, demonstrating ultra-slow light propagation stemming from the…
Photonic crystals as metamaterials
Stavroula Foteinopoulou
The visionary work of Veselago had inspired intensive research efforts over the last decade, towards the realization of man-made structures with unprecedented electromagnetic (EM)…
Broadband near-unidirectional absorption enabled by phonon-polariton resonances in SiC micropyramid arrays
G. C. R. Devarapu, S. Foteinopoulou
Inspired by moth eyes, nature's most powerful antireflex, we present a sub-wavelength SiC micropyramid design, which operates in the Reststrahlen band of SiC, namely the spectral b…
Negative refraction and superlensing in a 2D photonic crystal structure
R. Moussa, S. Foteinopoulou, Lei Zhang +4
We experimentally and theoretically studied a new left-handed (LH) structure based on a photonic crystal (PC) with a negative refractive index. The structure consists of triangular…
