Genome Ripple Modifier
The Ripple Modifier in 3ds Max creates a radial wave based on the Sine function with the distance of the vertex from the object's center as the argument.
Here is the replicated Ripple modifier with two Amplitude parameters, Wavelength and Phase (minus the Decay option):
In the left image, the green plane has the 3ds Max native Ripple modifier with Amplitudes of 20.0 and 10.0, Wavelenght of 50.0 and Phase of 0.0, while the blue plane has the Genome modifier with exactly the same settings. In the right image, the values are 0.0 and 10.0, Wavelength of 20.0:
