Efficient LU factorization exploiting direct-indirect Burton-Miller equation for Helmholtz transmission problems

Yasuhiro Matsumoto, Kei Matsushima

This paper proposes a direct-indirect mixed Burton-Miller boundary integral equation for solving Helmholtz scattering problems with transmissive scatterers. The proposed formulatio…

Injectivity of boundary integral operator in direct-indirect mixed Burton-Miller equation for wave scattering problems with transmissive circular inclusion

Yasuhiro Matsumoto, Kei Matsushima

This study proves that the injectivity condition for the integral operator of the direct-indirect mixed Burton-Miller (BM) boundary integral equation (BIE) for Helmholtz transmissi…
