Abstract

In this paper, a fast computation method is presented for computing electromagnetic scattering by thin strut-based ceramic lattice structures. In the proposed method, each thin ceramic strut of the lattice structure is first replaced by an impedance load modeled as a line of finite conductivity joining the two endpoints of the strut. Then the simplified model is discretized using the hybrid finite element-boundary integral-multilevel fast multipole algorithm (FE-BI-MLFMA). Numerical examples demonstrate the accuracy and efficiency of the proposed method.
