Abstract(in English) This paper describes on a boundary element method using the isogeometric analysis for electromagnetic wave scattering problems and its discretisation based on collocation. In our previous research we proposed that the EFIE~(Electric Field Integral Equation) and MFIE~(Magnetic Field Integral Equation), which are formulations of boundary integral equations for wave scattering problems with PECs~(Perfectly Electric Conductors), can be discretised with collocation by interpolating unknown functions with the B spline functions. In this paper we extend this numerical method to wave scattering problems with dielectric materials and show that a similar discretisation method is available for the PMCHWT~(Poggio-Miller-Chang-Harrington-Wu-Tsai) formulation, which is one of formulations of boundary integral equations for the scattering problems with dielectric materials.
