Bandgap Analysis of Photonic Crystal Model Error

Please login with a confirmed email address before reporting spam

Hello All,

I am trying to work my way through the Bandgap Analysis of Photonic Crystal model and run into an error:

Error: 6170
Failed to evaluate variable.
- Variable: lambda
- Global scope
Failed to evaluate expression.
- Expression: imag(lambda)
Failed to evaluate expression.
- Expression: -imag(lambda)/(2*pi)

I get the error both when I try to re-create the model from scratch using the RF Model documentation and also when I run the completed model from Comsol Model Library.

Am I suppose to define lambda? Anyone had luck reproducing the model's results?

Thanks,
Jacob
