The Fourier modal method for plasmonics
The FMM is characterized by expanding the EM field into Floquet-Fourier series and the medium into
Fourier series. Solve the Maxwell as equations as a matrix eigenvalue problem.
Advantage : Easy to write code and
For history reasons, There are lots of names to describe the FMM, such as RCWA, plane wave method,
different Method, and so on.
TWO breakthrough:
1. R-matrix or S-matrix
2. The convergence in TM polarization
Plasmonics is a branch of optical condensed matter science devoted to optical phenomenon on the
