Carbon Nanotubes Composite Materials for Dipole Antennas at Terahertz Range

Abstract

This paper aims to present two types of carbon nanotubes composite materials (CNTscomposite) for antenna applications within terahertz (THz) frequency band. These composite materials consist of CNTs coated by copper and silver, separately, to construct CNTs-copper and CNTs-silver composite materials, respectively. The comparisons between the dipole antennas of these structure materials with CNTs dipole antenna and copper dipole antenna are presented to exhibit performance evaluation of the presented new dipole antennas. The mathematical modeling of CNTs-composite material is presented in this paper. The results obtained from the comparisons CNTs-copper and CNTs-silver dipole antennas are presented based on S 11 parameters, gain and efficiency.

Interaction of spatial-Gaussian lasers with the magnetized CNTs in the presence of DC electric field and enhanced THz emission

“…The THz generation by using cross-focused Gaussian laser beams in the CNTs [28] also supports the results shown in the proposed scheme of THz generation. The simulation results in the THz investigation by Jurn et al [29] demonstrate that inter-spacing between the CNTs also makes a deep impact on the THz generation and this is in accordance with our findings.…”

Design of Carbon Nanotube Antenna in Nanoscale Range

“…Therefore, by inserting these material parameters in the available 3D EM simulation software packages, the EBM model can be designed and implemented [7] [9]. Complex permittivity approach had been applied to predict the electromagnetic properties of SWCNT-copper dipole antennas.…”

“…In order to predict the EM behavior of the SWCNTs-composite material, the important parameters of this material have been extracted. Hence, these parameters are utilized to represent the equivalent modeling approach of SWCNTs [7] [8].…”
