Abstract: Three experimental laser ultrasonic configurations—
line excitation with scanning detection, grating excitation
with single point detection, and grating excitation
with scanning probe beam—are shown to consistently reveal
the modified propagation properties of Lamb waves on
a polyethylene terephthalate (PET) film that is in contact
with different liquids on its two sides. Theoretical predictions
concerning the physical nature of different wave modes
in symmetric and asymmetric film loading configurations
(i.e., their existence, velocity, damping, and polarization)
are confirmed by the experimental results.
