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.…
