Theory of Supercritical Coupling and Generalized Bound States in the Continuum
Laser &Photonics Reviews, EarlyView.We develop a general theory of supercritical coupling and generalized bound states in the continuum (gBICs), revealing how interference between radiative and absorptive channels enables quality factors beyond conventional material‐loss limits. The framework unifies non‐Hermitian mode coupling, causality‐driven reactive interactions, and interference ...

Optimal Sensors Placement to Enhance Damage Detection in Composite Plates [PDF]
, 2014 This paper examines an important challenge in ultrasonic structural health monitoring (SHM), which is the problem of the optimal placement of sensors in order to accurately detect and localize damages.

Macromolecular Symposia, EarlyView.ABSTRACT Structural Health Monitoring (SHM) systems based on Guided Ultrasonic Waves are pivotal for the transition from damage tolerance to condition‐based design in aerospace Composite Fiber Reinforced Polymers (CFRP) components. However, environmental and operational variability poses a critical challenge for baseline‐free methods.

Analysis of Rayleigh wave interactions for surface crack characterization [PDF]
, 2012 Electromagnetic acoustic transducers (EMATs) have been used in pitch-catch mode for a better characterization of surface cracks in metals. The system, which combines the measurement of Rayleigh wave velocity in the in-plane and out-of-plane directions ...

FinTech and Environmental Sustainability: Evidence From Brazil
Sustainable Development, EarlyView.ABSTRACT This study explores the dynamic interplay between economic growth and environmental sustainability from a FinTech perspective, using Brazil as a case study. While FinTech's contribution to green transformation, sustainable finance, and resource efficiency has gained increasing attention, a notable lack of empirical research remains to assess ...

Three-dimensional edge waves in plates
, 2008 This paper describes the propagation of three-dimensional symmetric waves localized near the traction-free edge of a semi-infinite elastic plate with either traction-free or fixed faces.

Formation of Distance‐Based Orientation: Political Identity through Relational Positioning in Israel
Symbolic Interaction, EarlyView.Distance‐based orientation describes how pejorative labels may serve as anchor points for political identity. Existing research on political labeling has largely emphasized stigmatization, overlooking how labels may acquire durability and orienting capacity without losing pejorative force. Drawing on publicly circulating discourse, we trace positioning

Non-Semisimple Degeneracy of Lamb Waves
Mechanics of SolidsAbstract Anomalous guided waves appearing at a non-semisimple degeneracy of the fundamental matrix are observed and analyzed in the framework of the Cauchy sextic formalism. The non-semisimple degeneracy condition is explicitly constructed for the most general case of Lamb waves propagating in a traction-free ...
