In a microelectronics (packaged RFIC or SoC) context, what dielectric model would you advise or recommend to use in Clarity 3D? All dielectric materials are of Dispersive type (Piecewise Linear when Causality is not enforced; D-Sarkar and Debye when causality is enforced). Do you have public examples comparing measurement to simulation results?
What about a silicon bulk substrate when there is non null conductivity? D-Sarkar not applicable.
I would prefer to use constant dielectric characteristics over my frequency range (not extending higher than 60 GHz). Do you have any comment?
