Hi,
I have read so many posts about this problem but still can't seem to find an answer:
I'm trying to define my permittivity as frequency dependent in my material. I have an interpolation function of a local table of values with t being frequency and f(t) my permittivity. My function name is defined as epsr_SIRB, the units for argument and function are Hz and 1 respectively. My problem is that I can't seem to define my argument as frequency anywhere??? I tried defining permittivity in my material as epsr_SIRB(t) but COMSOL doesn't seem to recognize it. If I only write epsr_SIRB, COMSOL gives out an error of unknown variable. So my question is: how do I define my argument in the table correctly? Or better yet, how do I define this function in my material table so the values will be read?
Would appreciate any help! Jun
