Resumen:
A recursive computational procedure is developed to efficiently
calculate the macroscopic dielectric function of multicomponent
metamaterials of arbitrary geometry and composition within the long
wavelength approximation. Although the microscopic response of the
system might correspond to non-Hermitian operators, a representation of
the microscopic fields and of the response is developed, and an
appropriate metric that makes all operators symmetric is introduced.
This allows one to use a modified Haydock recursion, introducing complex
Haydock coefficients that allow an efficient computation of the
macroscopic response and the microscopic fields. The procedure is tested
by comparing the results with analytical ones in simple systems and
verifying whether they obey a generalized multicomponent Keller's and
the Mortola and Steffe's theorems for four-component metallic and
dielectric systems.
