Impedance Extraction using Effective Internal Impedance

 

Quasi-Static technique for skin-depth limited problems

 

External solvers: current-filament techniques

 

EII: rectangular bar

 

EII of triangular patch

 

Application in three dimensions: right angle bend

 

Example: bend in coplanar square conductors

 

Bend impedance for long arms

 

Coplanar bend: run time comparison

 

Total impedance for coplanar strips with bend

 

Coplanar meander line

 

Coplanar meander impedance

 

Surface ribbon method for 3-D impedance extraction
