Wave2000 Example #6:
Reflection, refraction and mode conversion studies.
This is an example designed to illustrate how Wave2000 simulates reflection
and refraction of an ultrasonic wave impinging on a boundary at an oblique
Here, a Gaussian modulated 1 MHz sine wave is generated by a 2 cm source transducer
located on the left edge of the object. The material on the left side of the
boundary (oriented at 30 degrees from the vertical) is polystyrene; the material
on the right side of the boundary is steel. In Wave2000, only the boundaries
between materials are shown during an ultrasound simulation, in order that
the propagating wave can be visualized.
As may be seen, both longitudinal and shear waves are reflected and transmitted
at the boundary between the two materials. The distinct angles of propagation
for the two modes are apparent from the simulation. If desired, one or more
receivers could be defined at arbitrary positions (even within the object)
to quantitatively measure the reflected/refracted ultrasound signals. You can
define both longitudinal and shear transducers in Wave2000 (i.e., a single
transducer can operate as both a longitudinal and shear source and/or receiver
simultaneously). In fact, any number of sources and receivers can be defined
within the same simulation!
These examples display only a small portion of the full features of Wave2000.
