Efficient space-domain formulation for integral equation modelling of printed metallizations on coated cylinders

Expressions for the spectral domain electric mixed potential (MP) Green's function for a cylindrical substrate are derived in terms of the spectral dyadic Green's function for the electric field. The spectral properties of the derived function are exploited in the transformation to the space domain extracting its spectral asymptotic behavior. The extracted asymptotic functions can be transformed analytically. Several important issues of software implementation, numerical stability and accuracy are briefly discussed.
