Characteristic of time-varying plasma sheath channel

It has been mentioned in several literatures that the plasma sheath is time-varying, which could be treated as a time-varying communication channel from the point view of communication and signal characteristic. A mathematical channel model is proposed with a dynamic stratified modelling method, and the channel characteristic features such as coherence bandwidth and coherence time are analysed in this paper. These channel characteristics are important in the selection and design of the communication system including the best transmitted data rate.
