Abstract :
In this paper, the hybrid volume-surface integral-equation(VSIE) approach is proposed to analyze the transmission and reflection characteristics of finite and curved frequency-selective surfaces (FSS) structures. The surface current and electric flux density is expanded by surface RWG and volume SWG basis functions, respectively. The multilevel fast multipole algorithm (MLFMA) is applied to reduce the computational complexity. Simulated results are given to demonstrate the accuracy and efficiency of the proposed method.
