Abstract
The article discussed the interface formed by the piezoelectric crystal and the vacuum. Considering the plane wave incident from the piezoelectric half space, five plane waves reflected back toward the piezoelectric media and two electromagnetic wave transmitted to the vacuum. Because these eight plane waves need to satisfy the electromagnetic and mechanical boundary simultaneous, we solved the weighting of each wave, then getting the pointing vector of each wave. The pointing vector stands for the energy carried by the plane wave per unit area per unit time. We express the electromagnetic energy radiated from the piezoelectric material by this energy flow discussed in this article.
