Sum

modelname

Sum

Model do not generate parameters. Model sum dielectric responses (suscetibilities) from two or more media. Resulting dielectric tensor is given as: $$ \varepsilon = 1 + \chi_1 + \chi_2 + \dots $$ where \(\chi = \varepsilon - 1\) is suscetibility.

attributes

• id1:id2:... - are identifiers of previously defined media.

Example

media:
  fL = Lorentz
  fD = Drude
  f = Sum:fL:fD
