ABSTRACT
Purpose: The purpose of the article was to broaden the knowledge about the behavior of Fibonacci superlattices
as filters electromagnetic waves.
Design/methodology/approach: Simulations of multi-layer systems is usually carried out by using two
complementary methods. The first, matrix method which allows the study of the properties of structures using
transmission maps and the second method used is the Finite-Difference Time Domain (FDTD) algorithm allows
on the study of electromagnetic wave propagation in the structure.
Findings: It can be seen that the lighting of the filter with monochromatic light in the wavelength range of the
band gap filter at the output causes propagation of low intensity in the range other than the wavelength of the
incident beam.
Research limitations/implications: The simulation was not considered the impact of losses in the material.
Practical implications: Present clear differences depending on the polarization allow the use of superlattices as
polarizers for specific ranges of wavelengths and angles of incidence.
Originality/value: Fibonacci superlattices have been pre-tested in. The purpose of the article was to broaden
the knowledge about the behavior of these structures as filters electromagnetic waves with a wavelength range
from the near infrared, the effect of the material surrounding the transmission and increasing knowledge of the
formation of band gaps.

1. Introduction
Quasiperiodic multilayer systems because of their unique
properties are used as filters of electromagnetic radiation and as
photonic materials are intensively studied in many research
centers all over the world [1-5]. There exists a phenomenon of the
photonic band gap, and therefore electromagnetic waves of
certain wavelengths do not propagate in the materials. The size
and the occurrence of band gaps is strongly correlated with the
