void GratingLayer1D::solve

(

string

method = "T"

)

[inherited]

solve layer with S- or T-Matrix approach

Calls the necessary functions to solve the layer after setting all parameters:

• CalculatePermitivity()
• createEigMat()
• solveEigMat()

additional, if the system is solved with the S-Matrix approach:

• calcSMatrix()

Parameters:
