In photonics, epsilon-near-zero (ENZ) metamaterials are engineered composites whose effective permittivity vanishes at designed frequencies. This zero-index condition decouples phase and wavelength, ...

Photonic band gap engineering in metamaterial structures exploits artificial materials with tailored subwavelength geometry to control the propagation of light. By arranging layers or inclusions of ...

Topological insulators (TIs) have fundamentally reshaped our understanding of materials by introducing robust boundary states arising from bulk topological invariants. Extending this paradigm, ...

A recent study published in the journal Nature Communications introduces a new class of electromagnetic materials called intrinsically nonlocal metamaterials. The researchers combined theoretical ...

From Thursday, 30 October to Tuesday, 4 November 2025, the PhoenixD Cluster of Excellence at Leibniz University Hannover and Heidelberg University will jointly host the 1 st workshop on Photonic ...
