Abstract: The present disclosure relates to a hysteretance component, which is designed based on its definition, calculation formulas, and port characteristics. By increasing or decreasing hysteretance components in a magnetic circuit, the intensity and effect magnitude of magnetic hysteresis in a vector magnetic circuit can be estimated and controlled from the perspective of magnetic circuit, allowing the vector state of a magnetic flux to be consistent with the desired state. Based on this, an application method is proposed, involving that a target magnetic circuit is formed by connecting reluctance, magductance, and hysteretance components in series, and magnetic circuit parameters of the three components are utilized to quantitatively express magnetization, eddy current, and magnetic hysteresis phenomena, enabling technicians to selectively alter the operating characteristics of the magnetic circuit, vector magnetic quantities, and power of the magnetic circuit by adjusting the parameters.

Abstract: A novel scatterer density-based predictive channel modeling method includes: obtaining channel data with different scenarios scatterer densities through a channel measurement or a simulation; obtaining corresponding channel statistical characteristic parameters through a data preprocessing based on the channel data; constructing a graph dataset by taking scatterer density in different scenarios as main characteristics to enhance a space-time correlation of data; dividing the graph dataset according to a certain proportion, and then using a graph attention network and a gated recurrent unit network to extract correlated channel space-time characteristics and implementing a cross scenario channel prediction. The method can capture channel variations in different scenarios, and obtain channel characteristics under different scatterer densities through high space-time correlated channel characteristics, and has good performance in channel prediction based on scenario.
