Wave scattering in frequency domain

Abstract

This report shows formulation of wave scattering in frequency domain. The formulation provides an understanding of S-matrix solver which is named as Scattering Matrix Analyzer (SMatrAn). The S-matrix has the whole of amplitude and phase information for reflected and transmitted waves from a complicated scatterer. Accurate S-matrix leads to quantitative evaluation of scattering wave. We can understand all formulas for the SMatrAn after reading this report. The S-matrix provided by SMatrAn will give us detailed analysis on complicated scattering in optical structure.
