Homogenized dynamic constitutive relation for Bloch-wave propagation in periodic composites: structure and symmetries
Central to the idea of metamaterials is the concept of dynamic homogenization which seeks to define frequency dependent effective properties for Bloch wave propagation. While the theory of static effective property calculations goes back about 60 years, progress in the actual calculation of dynamic effective properties for periodic composites has been made only very recently. Here we discuss th...
متن کاملHexagonal Shaped Body Wearable Textile Antenna on EBG Substrate Material
In this paper, a hexagonal shape wearable antenna is presented .the proposed antenna is having EBG structure embed in the inner substrate layer. The antenna resonates at 2.45 GHz. When antenna is incorporated with EBG cell structure, it shows improvement in gain by 1.9 dB and 33% bandwidth improvement. The EBG structure consists of just a 3x3 elements but reduces backward radiations considerabl...
متن کاملSymmetries in Hexagonal Quasigroups
When it doesn’t cause confusion, we can omit the sign “·”, e.g. instead of (a · b) · (c · d) we may write ab · cd. In this article, Q will always be a hexagonal quasigroup. The basic example of hexagonal quasigroup is formed by the points of Euclidean plane, with the operation · such that the points a, b and a · b form a positively oriented regular triangle. This structure was used for all the ...
متن کاملHexagonal projected symmetries.
In the study of pattern formation in symmetric physical systems, a three-dimensional structure in thin domains is often modelled as a two-dimensional one. This paper is concerned with functions in {\bb R}^{3} that are invariant under the action of a crystallographic group and the symmetries of their projections into a function defined on a plane. A list is obtained of the crystallographic group...
متن کاملGypsum Composites with CDW as Raw Material
Abstract—In this study, the feasibility of incorporating ceramic waste from bricks (perforated brick and double hollow brick) and extruded polystyrene (XPS) waste, is analysed. Results show that it is possible to incorporate up to 25% of ceramic waste and 4% of XPS waste over the weight of gypsum in a gypsum matrix. Furthermore, with the addition of ceramic waste an 8% of surface hardness incre...
