【摘要】：用金屬介質(zhì)表面電荷和電流分別代替電位和磁位,推導(dǎo)出非遲滯和遲滯情形下金屬介質(zhì)粒子散射的邊界積分方程;采用高階形函數(shù)處理離散后的邊界積分方程提高了解的精度;對(duì)不同形狀的介質(zhì)材料進(jìn)行粒子散射的數(shù)值模擬,數(shù)值解與解析解對(duì)比結(jié)果表明此邊界元法具有有效性.
[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.
