Nms carbon nanotubes11/21/2023 Copper dipole antenna does not offer reliable efficiency when it transmits or detects terahertz frequency signal because of skin effect. The trails of having a dipole antenna with the efficiency higher than the copper one have been made by researchers in recent years. To simulate SWCNTs-composite dipole antenna we used a time domain field. The behaviors of electric and magnetic fields within the structure in either time or frequency domain have been contained in CST Studio Suite software. Maxwell’s equations can be solved numerically inside the structure to make it simpler. Ĭomputer Simulation Technology is a powerful numerical full electromagnetic simulator. Hence, these parameters are utilized to represent the equivalent modeling approach of SWCNTs. In order to predict the EM behavior of the SWCNTs-composite material, the important parameters of this material have been extracted. The study of their EM properties is very important to offer new material for antenna design at different applications. The simulation of the equivalent modeling approach for SWCNTs-composite material is illustrated. New material structure (NMS) is presented to enhance antenna properties consisting of SWCNTs dipole antenna coated by a thin layer (in nm scale) of several materials separately as aluminum or copper. Quantitative predictions of the performance of CNTs antenna dipoles, including input impedance, and efficiency, are presented as a function of frequency. The complex permittivity approach has been adopted to know the constitutive parameters of the antenna material that will be modeled to become ready for the simulation. There are several methods for the investigation of the properties of the CNTs antenna. In this paper, a virtual CNTs model is developed to be used with commercial software packages to deduce the performance of various CNTs antenna configurations. The performance of CNTs dipole antennas has been investigated using comprehensive numerical techniques. Single wall carbon nanotubes (SWCNTs) were presented as a theoretical study to characterize the THz antenna based on combining the Boltzmann transport equation and Maxwell’s equations with boundary conditions of the electron distribution function. This assumption was presented, based on the idea that it can radiate as a small Nano-dipole antenna when it is electromagnetically exciting. ĬNTs have high electrical properties which make them distinguished from other materials. Researchers assumed that CNTs antennas technology will be at the frontier of scientific research for the next decades, especially in wireless communication technology with nanometer length of CNTs dipole antenna, the electromagnetic (EM) radiation from this antenna is expected to cover a range within terahertz (THz) and optical frequency. Carbon nanotubes (CNTs) have been investigated as antennas in various areas-communications between Nanodevices and macroscopic world, nano interconnect, fiber communication, aircraft and space communication systems.
