Design of a novel chiral fractal resonator

Abstract

In this paper, we presented a compact resonator using a planar chiral fractal tree structure, where the chirality and the fractal form can combine several features at once. The chiral properties of this resonator, which are discussed based on their optical activity, circular dichroism, and the effect of the number of the iteration. Our chiral fractal structure is of major interest in scientific research, their characteristics have given rise to interesting new applications. Numerical results are given and discussed to confirm.

Analysis of Graphene Pythagoras Tree Fractal Antenna with Thin SiO2 Substrate in Terahertz Regime

“…The table 1 provides the parameters of graphene. We use the Algorithm given by [11][12][13][14][15] to describe in detail how an arbitrary binary hierarchy can be recursively transformed into a Pythagoras Tree visualization (see fig. 1).…”

Miniaturized Quintuple Band Antenna for Multiband Applications

“…Use a patch antenna with inclined slots, tow grooves in the form of a rectangle on the circular surface of the disk, with an asymmetry gap of the coplanar waveguide (CPW) feeding structure [9], and a multi-branch structure is used in [10], whose each branch is tuned according to the resonance length of the desired frequency band and the coupling of each resulting branch into different bands. A slot enclosed in a rectangular patch in the form of a rectangular split-ring is used in [11,12], and a radar composed of two branches and a short stub is used in [13], but few internal multi-band antennas can cover more than three bands, including both WiMAX and WLAN bands [14][15][16][17][18][19][20][21][22].…”
