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…
Mathematical analysis of wave radiation by a step-like surface
Wangtao Lu
This paper proposes, for wave propagating in a globally perturbed half plane with a perfectly conducting step-like surface, a sharp Sommerfeld radiation condition (SRC) for the fir…
On Wellposedness and Convergence of UPML method for analyzing wave scattering in layered media
Wangtao Lu, Jun Lai, Haijun Wu
This paper proposes a novel method to establish the wellposedness and convergence theory of the uniaxial-perfectly-matched-layer (UPML) method in solving a two-dimensional acoustic…
