Local Robustness of Bound States in the Continuum through Scattering-Matrix Eigenvector Continuation
Ya Yan Lu, Jiaxin Zhou
We consider the diffraction of time-harmonic plane waves by a periodic structure, governed by the Helmholtz equation. Bound states in the continuum (BICs) are quasi-periodic fields…
Existence of Friedrich-Wintgen Bound States in the Continuum: Cavity with a Thin Waveguide Opening
Jiaxin Zhou, Wangtao Lu, Ya Yan Lu
Bound states in the continuum (BICs) are localized states embedded within a continuum of propagating waves. Perturbations that disrupt BICs typically induce ultra-strong resonances…
A Fourier-matching Method for Analyzing Resonance Frequencies by a Sound-hard Slab with Arbitrarily Shaped Subwavelength Holes
Wangtao Lu, Wei Wang, Jiaxin Zhou
This paper presents a simple Fourier-matching method to rigorously study resonance frequencies of a sound-hard slab with a finite number of arbitrarily shaped cylindrical holes of…
Resonance Frequencies of a Slab with Subwavelength Slits: a Fourier-transformation Approach
Jiaxin Zhou, Wangtao Lu
This paper proposes a novel, rigorous and simple Fourier-transformation approach to study resonances in a perfectly conducting slab with finite number of subwavelength slits of wid…
