Wave scattering in layered orthotropic media I: a stable PML and a high-accuracy boundary integral equation method
Yong Gao, Wangtao Lu
In anisotropic media, the standard perfectly matched layer (PML) technique suffers irrevocable instability in terminating the unbounded problem domains. It remains an open question…

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…
