1. An ion trap device, comprising:
an insulating substrate, the insulating substrate having a concave structure; and
at least two arc-shaped metal reflective electrodes, the arc-shaped metal reflective electrodes covering a front surface of the insulating substrate, the front surface being a concave surface, and the arc-shaped metal reflective electrodes being electrically insulated from each other, wherein
each of the arc-shaped metal reflective electrodes is configured to receive a RF voltage with a same frequency, a same phase and an adjustable amplitude.
