Abstract

Overall transmission characteristics of a microstrip line with an obliquely magnetized YIG-GGG thin film substrate including both the quasi-TEM and the MSW modes are investigated by using the finite-difference time-domain (FDTD) method solving the equation of motion of the magnetization vector simultaneously with the Maxwell´s equations in consistency. Nonreciprocal transmission characteristics of a microstrip line with an obliquely magnetized YIG-GGG film substrate normalized by fifty ohm are directly calculated by the FDTD method. The results are agreeable to the experimental results
