Abstract :
In this paper, a novel finite difference frequency domain (FDFD) algorithm is proposed for the analysis of substrate integrated waveguide (SIW) guided-wave problems where the perfectly matched layer (PML) has been chosen as the absorbing boundary condition and the Floquet theorem has been used to consider the periodic structure. Using the above method, the guided-wave problem is then converted to a generalized matrix eigenvalue problem and finally transformed to a standard matrix eigenvalue problem, which can be easily solved with many efficient available subroutines. Excellent agreements of numerical simulations and experimental results show the validity and efficiency of the proposed algorithm.
