资料General prototype network synthesis methods for microwave filters:一直想找些能够求得任意拓扑结构耦合矩阵的相关资料,难求!
看资料时发现了求耦合系数矩阵的一线希望:
Once the system function
is obtained the synthesis of the filter proceeds by extracting
element values [8] to obtain a coupling matrix.
希望大家能帮忙!
求:【8】“General prototype network synthesis methods for microwave filters,”
ESA J., vol. 6, pp. 193–206, 1982.
谢谢!!!!!!:30bb
这篇文章很难找:31bb :8de
求得任意拓扑结构耦合矩阵,这个很专业啊,不知道能够上哪个网站搜寻,
楼主不妨提示微友们一下,可能大家具有更多的针对性!

呵呵,我目前的进展是零,只是一直有那样的想法!!!因为GOOGLE和BAIDU资料是很难找到的!!!!有的话一定上传上来!!!!
任意拓扑结构耦合矩阵的相关资料,在网上很难找,不仿去万方等网站看看,但是下载需要收费,最好去书店看看
楼主的这篇文献没有找到。我提供作者Richard J. Cameron的其他几篇相应文章(论述 耦合矩阵),也不太好找哈。

一篇国外论坛上讨论的耦合矩阵求解的问题:
an example computation of coupling matrix for (Ref
R.J.Cameron 1999MTT Paper)
Parameters:
Infinit Zero
Number=4;
Zeros=(1.5 2.1);
Return Loss=24dB;
Double
terminated.
Please give me the results of each
step:
1,Polynomials for Y11,Y21
2,TNk,T1k,R1,R2
3,T after Schimidt
orthonormalization
4,Coupling Matrix got before matrix
reduction
5,Coupling Matrix after matrix reduction.
