A coupled-mode theory for two-dimensional exterior Helmholtz problems based on the Neumann and Dirichlet normal mode expansion
Kei Matsushima, Yuki Noguchi, Takayuki Yamada
This study proposes a novel coupled-mode theory for two-dimensional exterior Helmholtz problems. The proposed approach is based on the separation of the entire space R2 into a fict…

A topology optimization of open acoustic waveguides based on a scattering matrix method
Kei Matsushima, Hiroshi Isakari, Toru Takahashi +1
This study presents a topology optimization scheme for realizing a bound state in the continuum along an open acoustic waveguide comprising a periodic array of elastic materials. F…
