Analysis of Band Effects in One‐Dimensional Periodic Lattices Using an Enhanced Homogenization Method

open access: yesAdvanced Photonics Research, EarlyView.
An enhanced homogenization method for periodic lattices, applicable to any asymmetrical multipart structures, is proposed. This method simplifies intricate gratings into slab waveguides, predicts guided‐mode resonances and bound states in the continuum, without relying on numerical methods.

Mitigating Losses in Hyperbolic Asymptotic Eigenmodes

open access: yesAdvanced Photonics Research, EarlyView.
Herein, hyperbolic asymptotic eigenmodes, high‐k modes aligned with asymptotic directions in hyperbolic metamaterials, are introduced. By tuning permittivity tensors to balance loss compensation (Re(ε∥)/Re(ε⊥)=Im(ε∥)/Im(ε⊥))$\left(\right. \text{Re} \left(\right. \left(\epsilon\right)_{\parallel} \left.\right) / \text{Re} \left(\right.
