An ab initio electromagnetic framework links quasinormal modes to Fano resonances in extinction spectra. Analytical expressions for the Fano asymmetry and intensity parameters are derived from overlap integrals, enabling rapid spectral reconstruction and physical interpretation.

Loss Compensation and Coherent Virtual Absorption via Virtual Complex Frequency Wave Excitation
By establishing a mathematical bridge between real and complex frequencies, we present a general method for complex frequency wave excitation to obtain all electromagnetic responses at complex frequencies. Using properties of complex frequency waves, we compensate for the propagating loss of point sources and surface plasmon polaritons.

Resonant Acoustic Metamaterials
Acoustic applications of metamaterials have rapidly developed over the past few decades. The sound attenuation provided by metamaterials is due to the interaction between soundwaves and scatterers organized into a reticular grid, with a peak attenuation at a specific frequency band that is highly dependent on the scatterers’ diameter and reticular ...

We consider wave propagation along fluid-loaded structures which take the form of an elastic plate augmented by an array of resonators forming a metasurface, that is, a surface structured with sub-wavelength resonators.

Cuttlebone‐inspired metamaterials exploit a septum‐wall architecture to achieve excellent mechanical and functional properties. This review classifies existing designs into direct biomimetic, honeycomb‐type, and strut‐type architectures, summarizes governing design principles, and presents a decoupled design framework for interpreting multiphysical ...

A Bottom‐Up Design Framework for Multifunctional Lattice Metamaterials
This study introduces a generative AI framework for designing multifunctional lattice metamaterials. The method combines 3D Gaussian voxel generation with deep learning, enabling greater design freedom and structural performance. The optimized lattice metamaterials achieve enhanced energy absorption by 40–200% compared to conventional structures and ...

Auxetic Behavior in JUC‐530: The Effect of Interstitial Molecules on Framework Deformation
Auxetic behavior in the JUC‐530 covalent organic framework is predicted by molecular modeling to arise from a cooperative tetrahedral‐flattening mechanism within the framework topology. Guest molecule loading (N2, CH4, benzene) is shown to suppress the negative Poisson's ratio response.
