Analysis of Bleustein–Gulyaev wave propagation under thin periodic metal electrodes Journal Article uri icon



  • Bleustein–Gulyaev (BG) piezoelectric surface-wave propagation under a periodic metal-strip grating on piezoelectric cubic crystals is investigated. A general theory that fits both the elastic and electric periodic boundary conditions has been developed and is applicable to a grating with an arbitrary electrical connection between adjacent metal strips. Numerical examples are given for aluminum- and gold-shorted gratings on a gallium arsenide substrate. It is found that the BG waves which penetrate deep into the substrate in the absence of the metal grating become trapped at the surface when the grating is present. It is noted that the penetration depth is heavily dependent on the metal thickness. The relevant physical attributes of the wave such as particle displacement, electric potential, and dispersion are also computed and analyzed.
