Package Stripline - Surface Roughness m=1 m=0.5 HFSS simulation with no S.R. is not lossy enough. HFSS simulation with 1um S.R. calculation is too lossy. α’ c = α c [ 1 + (2/π tan -1 {1.4(Δ/δ s ) 2 })] HFSS simulation with 1um S.R. calculation, assuming half current distribution on rough side, fits measured data very well. α’ c = αc [ 1 + 0.5*(2/π tan-1 {1.4(Δ/δs ) 2 })]
