i'm getting this error in siwave validation check "Metal layer "layer-2" is embedded in a dielectric whose Er=0, but Er of dielectric above is 4.3 and Er of dielectric below is 4.3" but the values for dielectric constant are in there, while the loss tangent aren't. can someone explain this error why am i getting it?, what does it mean ? how to clear it? and how do i put the loss tangent values in?
