\"\"<\/p>\n

 I have chart above detailing the characteristics of the material which include: real permitivity , imaginary permitivity , real permeability, imaginary permeability. 
Then I gathered the data and put into excel file, from there, I work out the absolute value of permitivity\/permeability from the complex number<\/p>\n

For example: let say my real permittivity is 4 Imaginary permittivity is 1 => absolute permittivity will be √ (42+<\/sup>12<\/sup>) = 4.12<\/p>\n

Then I input this absolute value into HFSS.<\/p>\n

\"\"<\/p>\n

Now here is the issue.<\/p>\n

Some people said I should input the real permitivity instead and I don’t need to work out the absolute value like above?<\/p>\n

Some people said I should dividing the real permitivity by the vaccum permitivity instead then input the relative permitivity?<\/p>\n

Some say the data in my chart is already relative value?<\/p>\n

It is totally confusing to me, so can someone please help explain to me?<\/p>\n
