✦ Synopsis

demonstrate that the collision frequency c represents the loss mechanism of plasma.

4. CONCLUSION

The FDTD analysis of a plasma whip antenna has been presented in this paper and the main algorithm of the (FD) 2 TD implementation has been discussed. The numerical results show that the plasma frequency exercises a more significant effect on the deviation of the resonant frequency of the plasma antenna than the collision frequency and the latter significantly affects the magnitude of the return loss. Various dielectric effects must be taken into account for the design of plasma antennas. It has been demonstrated that plasma antennas offer a promising alternative to traditional metal antennas when the plasma frequency is much higher than the operating frequency.

For the propagating mode, the field is evanescent outside the dielectric. We expect the field to be very small when it reaches the PEC boundary. The difference in higher frequency is because the mesh in SOM is not as dense as that in finite-difference method. ## 4. CONCLUSION In this paper, the wa
