A copper wire wound on an iron rod called as an iron cored inductor. The impedance of an iron cored inductor can be varied by the different methods. In those, one of the methods is, placing an iron cored coil in the aluminium enclosure. Due to this, the effective impedance of an iron cored inductor is de-creased. If another coil is wound on the same core and placed in the aluminium enclosure, the induced EMF in another coil has increased. The detailed study of this effect is presented with numerical analysis in this paper.

In this paper an automated procedure for the analysis of Transparent Conductive Oxides (TCO) layers exhibiting rough surfaces is proposed. The method is based on the interaction between MATLand the Sentaurus TCAD and is aimed to the reduction of computational efforts needed for full three dimensional analyses. Experiments performed on CVD deposited ZnO layer, showing the reliability of the method for describing their optical properties, are reported. A semi-empirical technique for the extraction of the TCO refractive index is shown as well.
