N2 - In this paper, theoretically, the characteristics matrix method is
employed to investigate and compare the properties of the band gaps of
the one-dimensional ternary and binary lossy photonic crystals which are
composed of double-negative and -positive materials. This study shows
that by varying the angle of incidence, the band gaps for TM and TE
waves behave differently in both ternary and binary lossy structures.
The results demonstrate that by increasing the angle of incidence for
the TE wave, the width and the depth of zero-n, zero-\mu, and Bragg gap
increase in both ternary and binary structures. On the other hand, the
enhancement of the angle of incidence for the TM wave, contributes to
reduction of the width and the depth of the zero-n and Bragg gaps, and
they finally disappear for incidence angles greater than 50 and 60 for
the binary structure, and 40 and 45 for the ternary structures,
respectively. In addition, the details of the edges of the band gaps
variations as a function of incidence angle for both structures are
studied.
