  • Abstract
    For dielectric constants, only ε13 was significantly changed during correction prosess. This is because ε13 is small and have low influence on to capacitance. Mostly changed elastic constants are s12 and s23. Such a big change is due to low accuracy for these constants in resonance-antiresonance method. A mean for other constants change is about 6 %. Mostly changed piezoelectric constants are d31 and d32. Differences between measured and calculated SAW parameters are lower for corrected material constants.
