By Hwi Kim

Most on hand books on computational electrodynamics are desirous about FDTD, FEM, or different particular approach constructed in microwave engineering. against this, Fourier Modal approach and Its functions in Computational Nanophotonics is a whole consultant to the foundations and specific arithmetic of the up to date Fourier modal approach to optical research. It takes readers in the course of the implementation of MATLAB® codes for sensible modeling of recognized and promising nanophotonic constructions. The authors additionally tackle the restrictions of the Fourier modal method.

Features

  • Provides a accomplished advisor to the foundations, equipment, and arithmetic of the Fourier modal process
  • Explores the rising box of computational nanophotonics
  • Presents transparent, step by step, sensible causes on the way to use the Fourier modal process for photonics and nanophotonics purposes
  • Includes the required MATLAB codes, allowing readers to build their very own code

Using this publication, graduate scholars and researchers can find out about nanophotonics simulations via a entire remedy of the maths underlying the Fourier modal strategy and examples of sensible difficulties solved with MATLAB codes.
