Non-Uniform Distributed Parameter Field Line Coupling Model for High-Power Microwave

In this paper, based on the classical low frequency field line coupling model and the high frequency transmission line distribution parameter model in the transmission line super theory, a high frequency field line coupling model with non-uniform distribution parameters for high-power microwave (HPM) is proposed. In this model, the distribution parameters of the line varying with the position can be used to describe the coupling characteristics of the transmission line, and the load response current generated by HPM can be quickly calculated on a line by combining with the finite difference time domain method. Compared with the classical low frequency field line coupling model, the proposed model in this paper is more consistent with the load response current waveform calculated by CST.
