High frequency vibration exciter

I want to use a vibration shaker to excite a steel sheet up to 100kHz. Is it possible?
Anyboday has such experience?

Anything is possible! What is your goal for exciting the sheet? You could think about plate waves. Where the thickness of the steel sheet is close to the wavelength of 100 KHz in your steel. Or if you have a given sheet, calculate back to the frequency required to induce a plate wave.

Depending on how much energy is required would determine which vendor's product is best suited for your application

Re: High frequency vibration exciter
E, thank you for your answer. It's good news for me. I just want to excite the structure to such high frequency and measure the vibration energy on that frequency band. since the sheet is small (1"X8"X1/16") and I guess the energy should be little.
Would you suggest some products/vendors?

Mini Vibration exciter
Hello!I wish to develop a mini vibration exciter which generate around 5 Newton. This shaker will be placed at the shaft bearing of a 2 stroke motorcycle engine. Purpose of this project is to do the vibration analysis of the 2stroke engine by eliminate the vibration due to the combustion inside the engine itself.
