I want to design a PLASMA antenna for microwave frequency. Is there any manual i can find about it. Please do let me know

For CST, (cold) plasma can be described using the drude model. There are a couple of macros that help you set it up.
@nisarg thank you
@marcelo is there any manual which i can download in which each step is mentioned? i know about the drude model but i want to see a exact manual.
Hi Mr. Khan
See pls. if these pdf's can help you. Some step-by-step procedures are presented.
we found another model of the plasma antenna based on HFSS, which is a useful tool in the field of antenna design. When setting up the model, we should pay attention to the dielectric constant and the conductivity of the plasma, because they are both involved with the electron density, the collision frequency, and the communication signal frequency. For the plasma antenna with the liner distribution of electron density, its dielectric constant and conductivity vary axially even with the same communication signal frequency. Here, to be convenient for simulation, the plasma antenna is divided into sufficient segments, in which the electron density is assumed uniform. As a result, the dielectric constants and conductivities of adjacent segments will have a little discrepancy. These settings will benefit the veracity of the simulation. Figure (attached) is the HFSS model of the plasma antenna, which is put on an infinite metallic plane. The air volume object is defined as a radiation boundary, at which waves are absorbed completely, essentially ballooning the boundary infinitely far away from the antenna. At the end of the antenna, a lumped port is assigned.
