1. It indicates that the soil-mine system's resonance and antiresonance mechanisms exist concurrently.

2. The relationship between the resonance frequency, the antiresonance frequency, the effective electro-mechanical coupling coefficient and the radius ratio is analyzed.

3. The antiresonance frequency formula in a round film is presented and analyzed.

4. The numerical results show that LQR could control the power flow transmission at the natural frequencies of the coupled system, but increase power transmission at the antiresonance frequencies.

5. A new vibration griddle which is working on the driving point antiresonance state is put forward.
