Notes:
The ferroelectric domain layer wave (FDLW) guide, B-G surface waveguide, and ferroelectric domain wall (M-T) waveguide were made by poled PZT ceramics. The waveguide properties of these waveguides were measured and compared. The FDLW waveguide has the lowest transmission attenuation in the frequency range (200–800 kHz) of these measurements. Due to its low transmission loss and function of modulation of amplitude, the FDLW waveguide has a better ratio of the realizable minimum insertion loss to relative maximum bandwidth than the other two structures in the frequency range of the measurements. Experimental dispersion curves measured by a phase shift method have been correlated with the theoretically predicted dispersion. The analysis demonstrates that the nature of the changes in dispersion is associated with the changes in the dielectric and piezoelectric properties of PZT.
