ACOUSTIC SURFACE LEAKY WAVE PROPAGATION UNDER PERIODIC METAL GRATING

The properties of LSW propagation under Periodic metal grating have been investigated by using a new method of field analysis that leads to a satisfactory solution fitting the electrical boundary conditions. The detailed dispersion relation and the curves of attenuation constant for LSW on 49°Y-X LiNbO₃ are presented. The discussion and comparison between the theory and experiment for the first stopband are also made.
