The MASC offers a capability similar to ultrasonic memory correlators. The device is very easy to construct, operates naturally at the frequency range of the normal ultrasonic testing devices and potentially offers a very high pulse compression ratio, in the range of millions. However some aspects such as noise dynamic range, linearity and spurious responses due to reflections need to be studied before final applications can be foreseen. The research is continuing to clarify these aspects as well as the different material choices for the magnetoacoustically active rod. Other systems such as surface and string wave magnetoacoustic correlation devices are being considered.
