N2 - As an advanced ferroelectric material, barium titanate (BaTiO3) crystal has an electro-optic effect higher than lithium niobate (LiNbO3) crystal by 20-40 times, so it has been taken to be one of the best materials to realize the ultra-high bandwidth electro-optic modulators. In this paper, we model and simulate the transmission coefficient S21 of the microwave signal to the frequency of drive microwave through an embedded waveguide-electrode structure, and further simulate the S21 with a software tool-Sonnet. As a result, when the electrode length, electrode width, electrode thickness, electrode gap, BaTiO3 thin film thickness, magnesium oxide (MgO) substrate thickness and embedded depth were 1mm, 80μm, 1μm, 8μm, 450nm, 500μm and 0.1μm, respectively, the electro-optic modulation bandwidths have reached 50-70GHz, and it can be optimized to 100GHz at 250μm MgO substrate thickness.
