| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In finite element method (FEM) for electromagnetic wave simulation of open-system problem, it is necessary to absorb the electromagnetic wave at the end of the analysis region without reflection, or connect an infinite uniform waveguide at the end boundary. In the former case, it can be realized by imposing a perfectly matched layer (PML), however, it is necessary to expand the computational window to secure the PML region, and calculation cost becomes high. In the latter case, the eigenmode expansion was conventionally used. Although this technique can accurately calculate both guided and radiation modes, calculation for large number of modes is requred and calculation cost becomes enormous accordingly. In this paper, we present efficient boundary condition of FEM for terminating computational domain by using propagation operator without extra PML absorbing region and any mode expansion. | |
