What is it about?
This open terahertz wave transmission model in plasma means that any distribution of real plasma data can be imported into the model, and the transmission characteristics of any frequency band of terahertz waves in these real plasmons can be quickly obtained through simulation calculation. This model can also be extended to study the transmission characteristics of microwave and infrared wavelengths in real plasma.

Why is it important?
This paper presents an open computational model for the study of electromagnetic wave propagation in plasma. You can quickly understand the transmission characteristics of electromagnetic waves such as microwaves, terahertz waves, and even infrared light in real plasma with any arbitrary distribution with this model. It provides technical reference for selecting reasonable communication electromagnetic frequency to solve the problem of communication blackout.
Perspectives
The simulation of this open model can avoid the problem that the signal-to-noise ratio of the current terahertz test system is not high enough and difficult to measure accurately. It can help to quickly grasp the real characteristics of terahertz communication in various non-uniformly distributed real plasmas. Considering the electron density, collision frequency and other key factors of plasma, it is suitable for the study of transmission characteristics of electromagnetic waves in various frequency bands in plasma, and has great popularization value.
