abstract

The reflection and transmission theory of waves in pyroelectric medium is studied in this paper. In general in an infinite homogeneous pyroelectric medium there are four bulk wave modes: quasi-longitudinal, two quasi-transversal and temperature waves. However there are five boundary conditions in the reflection and transmission problem of the pyroelectric medium. In this paper we find that the surface wave will be revealed to satisfy the boundary conditions with other four bulk waves. The surface wave has the same wave vector component with the incident bulk waves on the interface plane. The two dimensional reflection problems of waves at the interface between the semi-infinite pyroelectric medium and vacuum is researched and an numerical example is given.
