Ultrasonic Position Measurement
The primary purpose of this thesis is to use several ultrasonic receivers and transmitters to
implement a position measurement system. By combining range measurements from several receivers
and knowing the position of the receivers relative to each other it is possible to use
triangulation theory to implement the proposed position measurement system.

Ultrasonic Lamb-wave Devices Based on PZT Thin Films
A very thin suspended composite membrane along which acoustic waves are generated and detected,
surrounded by a solid thick silicon frame, is the key component of a so called Lamb-wave sensor
and/or actuator. The interdigital transducers patterned on the piezoelectric PZT layer allows the
transformation of a voltage signal into a mechanical deformation and vice versa. Any external
perturbations that induce a selective variation of the synchronous frequency can be investigated,
e.g. temperature, pressure, added mass, electric field, shock, stress.

Ultrasonic Inspection Simulation at SwRI
The multi-Gaussian beam model is an analytical solution of Gaussian wave propagation and it uses
paraxial approximation. Such an analytical solution has made this beam model very computationally
efficient. The MGB model can compute the propagation of ultrasound from planar or bi-cylindrically
focused elliptical-element transducers. This model can also propagate ultrasound through curved
interfaces in non-symmetry planes.
