Abstract EN
The radiation characteristic of plasma antenna is investigated by using the finite-difference time-domain (FDTD) approach in this paper.
Through using FDTD method, we study the propagation of electromagnetic wave in free space in stretched coordinate.
And the iterative equations of Maxwell equation are derived.
In order to validate the correctness of this method, we simulate the process of electromagnetic wave propagating in free space.
Results show that electromagnetic wave spreads out around the signal source and can be absorbed by the perfectly matched layer (PML).
Otherwise, we study the propagation of electromagnetic wave in plasma by using the Boltzmann-Maxwell theory.
In order to verify this theory, the whole process of electromagnetic wave propagating in plasma under one-dimension case is simulated.
Results show that Boltzmann-Maxwell theory can be used to explain the phenomenon of electromagnetic wave propagating in plasma.
Finally, the two-dimensional simulation model of plasma antenna is established under the cylindrical coordinate.
And the near-field and far-field radiation pattern of plasma antenna are obtained.
The experiments show that the variation of electron density can introduce the change of radiation characteristic.
