Symmetric and Asymmetric Analysis of Graphene Based Antenna Using Kinetic Theory of Plasma

In this research, Graphene-based plasmonic nano antenna with symmetric and asymmetric structures are analyzed in the Terahertz range. Recent research on Graphene shows a huge amount of potential in microwave and millimeter wave applications due to its tunability properties. The Graphene nanoantenna is analyzed in plasmonic using the kinetic theory of plasma with the Vlasov equation which has further applications in Biomaterials, Sensors and in Quantum Mechanics. SPP waves are generated due to third-order nonlinearity present in Graphene. The kinetic theory of plasma gives solutions to Fermi-level perturbations that cause charge transport in the plasmonic cavity. The change in the Fermi levels is generated by artificially designed symmetric asymmetric structures. The change causes electron and hole transport. Breaking the symmetry in the patch antenna also leads to the quantum phenomenon. The quantum transport between the left and right arms of antennas or source and drain causes the heavy flow of charges that makes the plasmonic antenna radiate. These antennas are of significance in various applications as absorbers, electromagnetic shielding, linear nonlinear waveguides, photodiodes, rectennas and quantum mechanics. The devices of Graphene are in demand due to their low power dissipation and increased sensitivity. Various antenna scattering radiation patterns and absorption peaks in the Terahertz range from (3-20 THz) are shown for different symmetric, asymmetric antennas. The conductivity and current are given in terms of the kinetic theory of plasma and quantum wave phenomenon. Due to Graphene's high-frequency operations at nanostructures, the antennas are better in control as compared to large sizes of metal and copper antennas at high frequencies. These antennas are more flexible giving better tunability by controlling the applied voltages. Due to this, the antennas are more suitable for biomedical applications and THz applications.
