摘要

为研究多层同轴电缆的场传播特性，提出了一种高效、准确的时域有限差分仿真技术。该技术将均匀时域有限差分格式与分段线性递推卷积方法相结合，用于处理具有极高介电常数的色散层中的场。该方法已经开发并测试了径向对称圆柱系统，并打算在未来的3D应用中使用。

Efficient FDTD simulation of fields in coaxial cables with multi-layered insulation partially formed by dispersive layers of extremely high permittivity

An efficient and accurate FDTD simulation technique for investigation of field propagation in multi-layered coaxial cables has been developed. This technique combines a uniform FDTD scheme with the piecewise linear recursive convolution method, which is applied for the treatment of fields in dispersive layers, having extremely high permittivity. The method has been developed and tested for a radial symmetric cylindrical system and is intended for future use in 3D applications.
