标题: HFSS solution type (求解类型) 经验谈 [打印本页] 作者: Xuxingfu 时间: 2015-1-24 14:43 标题: HFSS solution type (求解类型) 经验谈 这里只针对modal driven 和 terminal driven做分析，至于eigenmode是解析谐振频率的，如滤波器，这个大家想必都了解。但是模式驱动，终端驱动这两个分析类型该如何区分呢。很简单，hfss fullbook里面讲了这样一段话“The Modal S-matrix solution computed by Ansoft HFSS is expressed in terms of the incident and reflected powers of the waveguide modes.This description does not lend itself to problems where several different quasi-transverse electromagnetic modes can propagate simultaneously. For structures like coupled transmission lines or connectors, which supportt multiple quasi-TEM modes of propagation,if is often desirable to compute the Terminal S-Parameters.”其简约意思是讲：模式驱动对应的它的模式S参数矩阵是入射功率和反射功率的描述，但是这种模式S参数不能用于解决多准TEM模式，在这里大家一定要注意several 和quasi这两个单词，several不是1个，而是指多个，而quasi是准TEM，而不是TEM。因而后面就说了for structure like耦合传输线或连接器是需要terminal drien来分析的， 4 O5 h; K/ Y5 E/ j' V4 V, w$ I/ N& U' r) O
故得出结论： # Q9 o- C+ d& Y1 l# r7 Y" a
