Rayleigh-wood anomalies
WebBy interpreting the extraordinary transmission phenomenon on the basis of induced surface currents, the potential of engineering Rayleigh-Wood anomalies is shown, or more specifically, moving down the resonant peak away from the Rayleigh-Wood's anomaly. WebAs it will be seen in the following, Wood’s discovery immediately raised consid-erable attention and the fascination of many specialists of optics for the so-called Wood’s anomalies never died. Rayleigh proposed the first explanation for the exis-tence of the anomalies [2, 3]: an anomaly in a given spectrum occurs at a wavelength

WebInstitute of Physics WebDec 28, 2024 · We report on the observation of emerging beam resonances, well known as Rayleigh-Wood anomalies and threshold resonances in photon and electron diffraction, respectively, in an atom-optical diffraction experiment. Diffraction of He atom beams reflected from a blazed ruled grating at grazing incidence has been investigated.
Webdark and bright bands (Wood anomalies) in diffraction patterns of white light from ruled reflection gratings. Rayleigh in 1907 first traced back Wood anomalies to grazing emergence of a diffracted beam [2]. Thus, the term Rayleighconditions (Rayleigh wavelength, Rayleigh angle) refers to conditions for grazing beam emergence where … WebIn this article, we demonstrated narrow-band high-order resonances enabled by Rayleigh anomaly in the nanohole arrays that are fabricated by scalable colloidal lithography. ... direct detection of a single monolayer of biomolecules with naked eye using these Fano resonances and the associated Wood’s anomalies.
WebHere, we show that high Q-factor magnetic dipole resonance at THz frequencies can be achieved by exploiting the coherent Fano interactions with strong field enhancements in an array composed of single metallic split-ring resonators, working at Wood-Rayleigh anomalies. It can give rise to ultrahigh Q-factor beyond 104 in the THz regime.
WebMany effects, e.g., the surface lattice resonance, are based on Wood’s anomalies discovered more than a century ago [13] and later interpreted by Rayleigh [14] and Fano [15]. Optical biosensing most often includes monitoring of the change in the refractive index during deposition of biological molecules onto the nanoparticle surface. dynalife waiting timeWebA new theory of Wood’s anomalies is presented which is based on a guided wave approach rather than the customary multiple scattering procedure.
