【摘要】：用金属介质表面电荷和电流分别代替电位和磁位,推导出非迟滞和迟滞情形下金属介质粒子散射的边界积分方程;采用高阶形函数处理离散后的边界积分方程提高了解的精度;对不同形状的介质材料进行粒子散射的数值模拟,数值解与解析解对比结果表明此边界元法具有有效性.
[Abstract]:The boundary integral equations of particle scattering in the case of non-hysteresis and hysteresis are derived by replacing the potential and magnetic potential with charge and current on the surface of metal medium, and the accuracy of the solution is improved by using high-order shape function to deal with the discrete boundary integral equation. The numerical simulation of particle scattering of dielectric materials with different shapes is carried out. The comparison between the numerical solution and the analytical solution shows that the boundary element method is effective.
