dc.description.abstract | This paper presents an efficient method to compute
the dispersion diagram of periodic and uniform structures with
generic anisotropic media. The method takes advantage of the
ability of full-wave commercial simulators to deal with finite
structures having anisotropic media. In particular, the proposed
method ¡extends the possibilities of commercial eigenmode solvers
in the following ways:¡ (i) anisotropic materials with non-diagonal
permittivity and permeability tensors can be analyzed; (ii) the
attenuation constant can easily be computed in both propagating
and stopband regions and lossy materials can be included in
the simulation; and (iii) unbounded and radiating structures
such as leaky-wave antennas can be treated. The latter feature
may be considered the most remarkable, since the structures
must be forcefully bounded with electric/magnetic walls in the
eigensolvers of most commercial simulators. In this work, the
proposed method is particularized for the study of liquid crystals
(LCs) in microwave and antenna devices. Thus, the dispersion
properties of a great variety of LC-based configurations are
analyzed, from canonical structures, such as waveguide and
microstrip, to complex reconfigurable phase shifters in ridge gap waveguide technology and leaky-wave antennas. Our results have
been validated with previously reported works in the literature
and with commercial software CST and HFSS. | es |
