Abstract

A new method is introduced to analyze lossy Inhomogeneous Planar Layers (IPLs). In this method, the equations of IPLs are converted to the equations of homogeneous planar layers, which have been excited by distributed equivalent sources. Then, the electric and magnetic fields are obtained using an iterative approach. The validity of the method is verified using a comprehensive example.
