Whenever an ultrasonic wave encounters a boundary between two media it is partially reflected
and refracted, as any acoustic wave would be. Unlike light, the wave also undergoes mode
conversion so that in the general case a single incident wave could produce two reflected waves
and two refracted waves. The angles which define the path of the wave are determined by
Snell’s law and are easily calculated. The relative amplitudes, on the other hand, require quite
complicated formula when the angle of incidence is anything other than 0 degrees. This problem
gets compounded when the angle of the incident wave goes beyond the first critical angle. At
this point the angle of the refracted wave becomes imaginary and the equations to calculate
the relative amplitudes become complex. This paper describes a tool that has been developed,
using a spreadsheet, which performs the calculations for all incident angles. The user selects the
media and the type of incident wave and the resulting waves are shown graphically as well as
numerically. The tool was developed primarily as part of an undergraduate course on ultrasonic
testing, but could be used more widely.
