stackfield - Script command – Lumerical

Calculates the fields within a multilayer stack illuminated from below by a plane wave using the analytic transfer matrix method. This function returns the E and H fields (Es, Ep, Hs, Hp). All results are returned in a single dataset as a function of frequency, incidence angle and location in the stack (z).

Syntax

Description

field = stackfield(n,d,f);

Arguments for a stack with Nlayers:

n: Refractive index of each layer. Size is either Nlayers, or Nlayers x length(f) if dispersive materials are involved.

d: Thickness of each layer. Size is Nlayers.

f: Frequency vector.

field = stackfield(n,d,f,theta,res);

theta: Angle vector, in degrees. Optional, default is 0.

res: resolution in the field result returned. Optional, default is 1000.

field = stackfield(n,d,f,theta,res,min,max);

min/max: the min/max position where the user wishes to compute the field. 0 corresponds to the bottom of the stack. Optional, default is the span of the multilayer stack.

Example

See stackrt.
