How do you account for imaginary part of permittivity in CST while defining a new material? In the dialogue box where you input the value for permittivity of the dielectric used, when defining a normal material, I've tried using imaginary numbers (eg: 3+2i). Can anyone let me know is this the right way to account for the dielectric loss in a substrate/dielectric? And if this is the only way, does CST support the mathematical expression (x+yi) as I didn't get any difference in S21 (insertion loss).
