Hello everyone, while I was designing a sinusoidal metastructure I faced several issues, first of all the equation has three parameters, amplitude, wavelength and no of cycle. current equation driven design seems doesn't support three rather one only. I would be very grateful if anyone could help me with the problem to get desired solution. Thanks in advance.
