Experimental evidence of guided resonances in photonic crystals with aperiodically-ordered supercells [PDF]

, 2010
We report on the first experimental evidence of guided resonances (GRs) in photonic crystal slabs based on aperiodically-ordered supercells. Using the Ammann-Beenker (quasiperiodic, 8-fold symmetric) tiling geometry, we present our study on the ...

Time‐Domain Near‐Field Scanning Microscopy of Terahertz Metasurfaces

Advanced Photonics Research, Volume 7, Issue 1, January 2026.
Time‐domain near‐field scanning terahertz microscopy provides direct access to subwavelength electromagnetic fields on metasurfaces. By combining controlled polarization excitation with nanoscale probing, this technique enables quantitative visualization of localized hotspots, surface‐wave propagation, and wavefront manipulation, offering a powerful ...

Holographic assembly of quasicrystalline photonic heterostructures

, 2005
Quasicrystals have a higher degree of rotational and point-reflection symmetry than conventional crystals. As a result, quasicrystalline heterostructures fabricated from dielectric materials with micrometer-scale features exhibit interesting and useful ...

Bloch–Landau–Zener Oscillations in Moiré Lattices

Fortschritte der Physik, Volume 73, Issue 11, November 2025.
Abstract A theory of two‐dimensional Bloch–Landau–Zener (BLZ) oscillations of wavepackets in incommensurate moiré lattices under the influence of a weak linear gradient is developed. Unlike periodic systems, aperiodic lattices lack translational symmetry and therefore do not exhibit a conventional band‐gap structure.

Understanding the Role of Trapezoids in Honeycomb Self‐Assembly—Pathways between a Columnar Liquid Quasicrystal and its Liquid‐Crystalline Approximants

Angewandte Chemie, Volume 136, Issue 6, February 5, 2024.
T‐shaped polyphiles self‐assemble into a liquid quasicrystal and a series of liquid‐crystalline periodic approximants, all representing polygonal honeycombs formed by the stacking of p‐terphenyls. Featuring giant octagonal motifs containing non‐regular trapezoidal or pentagonal with regular triangular and square tiles, the phases assume a transition of
