  Abstract

In this paper, wave propagation characteristics of microstrip resonator and coupled microstrip lines are analyzed using finite-difference time-domain method. The substrate layers consist of a magnetized ferrite subsrate and a dielectric subsrate. The modified generalized theory of perfectly matched layer is applied at the most outer boundary of ferrite to seek credible analysis. In a microstrip coupled line, which is magnetized in transverse or longitudinal direction to the direction of wave propagation, scattering parameters are calculated. For a microstrip resonator, resonance characteristics as a function of magnetic bias field are analyzed. A comparison of the two-dimensional FDTD results and the three-dimensional FDTD results on resonance frequency is accomplished. The electrical tune of MSW devices is verified by these results.
