基于低温共烧陶瓷工艺的一种新型层叠式多层结构的波概念迭代方法研究

Analysis of a new kind of LTCC cascade multilayer structure by wave concept iterative process

提出了基于波概念的一种有效迭代方法,详细给出了波概念迭代法(wave concept iterative process)理论推导公式,并用来处理基于低温共烧陶瓷工艺的新型多层结构计算问题,涉及到了混合磁场与电场方程,包括基于一种简单形式的匹配负载模拟上的S参数提取问题.利用matlab语言编写程序,从而确定S参数的频率响应,并将数值结果与仿真结果进行比较,两者呈现出很好的一致性,同时验证了波概念迭代法相对于其他算法的优势所在.

In this paper, an efficient new method named wave concept iterative process （WCIP） based on transformation between space domain and spectral domain is introduced. The derived WCIP theory formulation is presented in detail. A new kind of LTCC multilayer structure is analyzed using the iterative method. The approach involves the mixed magnetic and electric field equation and S parameter extraction technique based on a simple form of matched load simulation. The whole process is illustrated by MATLAB programming, so that frequency response of S parameter is determined. The numerical results are compared with the simulation results and good agreement shows the validity and usefulness of the iterative method given in this paper.
