Fourier-Galerkin method for scattering poles of sound soft obstacles
Yunyun Ma, Jiguang Sun
The computation of scattering poles for a sound-soft obstacle is investigated. These poles correspond to the eigenvalues of two boundary integral operators. We construct novel deco…
Computation of transmission eigenvalues by the regularized Schur complement for the boundary integral operators
Yunyun Ma, Fuming Ma, Yukun Guo +1
This paper is devoted to the computation of transmission eigenvalues in the inverse acoustic scattering theory. This problem is first reformulated as a two by two boundary system o…
Computing Integrals Involved the Gaussian Function with a Small Standard Deviation
Yunyun Ma, Yuesheng Xu
We develop efficient numerical integration methods for computing an integral whose integrand is a product of a smooth function and the Gaussian function with a small standard devia…
Computing Highly Oscillatory Integrals
Yunyun Ma, Yuesheng Xu
We develop two classes of composite moment-free numerical quadratures for computing highly oscillatory integrals having integrable singularities and stationary points. The first cl…
