A topology optimisation of acoustic devices based on the frequency response estimation with the Padé approximation
Yuta Honshuku, Hiroshi Isakari
We propose a topology optimisation of acoustic devices that work in a certain bandwidth. To achieve this, we define the objective function as the frequency-averaged sound intensity…
A shape optimisation with the isogeometric boundary element method and adjoint variable method for the three-dimensional Helmholtz equation
Toru Takahashi, Daisuke Sato, Hiroshi Isakari +1
This paper presents a shape optimisation system to design the shape of an acoustically-hard object in the three-dimensional open space. Boundary element method (BEM) is suitable to…
An isogeometric boundary element method for three-dimensional doubly-periodic layered structures in electromagnetics
Toru Takahashi, Tetsuro Hirai, Hiroshi Isakari +1
This paper proposes an isogeometric boundary element method (IGBEM) to solve the electromagnetic scattering problems for three-dimensional doubly-periodic multi-layered structures.…
