Bruggeman formula

modelname

Bruggeman

Model generate a parameter \(p\), packing density factor of second medium. Resulting dielectric function is given as: $$ \varepsilon = d \pm s $$ where$$ d = \varepsilon_1 \left(\frac{1}{2} - \frac{3}{4} p\right) - \varepsilon_2 \left(\frac{1}{4} - \frac{3}{4} p\right) $$ $$ s = \sqrt{ \frac{d^2}{16} + \frac{1}{2} \varepsilon_1 \varepsilon_2 } $$

attributes

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

Example

media:
  f1 = Lorentz
  f2 = Lorentz
  f = Bruggeman:f1:f2
