Accessing both electrochemical SEIRA and SERS with ultrasensitive metamaterials for enhanced molecular identification
Nicolas Spiesshofer, Tabitha Jones, Sarah May Sibug Torres +11
Surface-enhanced IR absorption (SEIRA) and surface-enhanced Raman spectroscopy (SERS) are complementary techniques that allow for ultrasensitive chemical fingerprinting. Non-invasi…
Extreme mid-infrared field enhancement and anapoles in high-index plasmonic metamaterials
Zoltan Sztranyovszky, Nicolas Spiesshofer, Caleb Todd +5
High-refractive-index materials underpin a wide range of optical technologies, including communications, imaging, lasers, and integrated photonic systems. Here, we demonstrate a se…
Extending completeness of the eigenmodes of an open system beyond its boundary, for Green's function and scattering-matrix calculations
Zoltan Sztranyovszky, Wolfgang Langbein, Egor Muljarov
The asymptotic completeness of a set of the eigenmodes of an open system with increasing number of modes enables an accurate calculation of the system response in terms of these mo…
Exceptional Bound States in the Continuum
Adrià Canós Valero, Z. Sztranyovszky, E. A. Muljarov +2
Bound states in the continuum (BICs) and exceptional points (EPs) are unique singularities of non-Hermitian systems. BICs demonstrate enhancement of the electromagnetic field at th…
First-order perturbation theory of eigenmodes for systems with interfaces
Zoltan Sztranyovszky, Wolfgang Langbein, Egor A. Muljarov
We present an exact first-order perturbation theory for the eigenmodes in systems with interfaces causing material discontinuities. We show that when interfaces deform, higher-orde…
Quantitatively linking morphology and optical response of individual silver nanohedra
Yisu Wang, Zoltan Sztranyovszky, Attilio Zilli +4
The optical response of metal nanoparticles is governed by plasmonic resonances, which are dictated by the particle morphology. A thorough understanding of the link between morphol…
