Abstract

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.
