XFdtd 7.10 新功能

REMCOM 于2021年十二月2推出了新版的XFdtd 7.10 这个重大更新，添加了电路编辑器等重要功能，并对之前版本进行除错，提升软件质量与效能。

新版本支持Linux RHEL7.5同时移除了对Windows 7 和Windows 8 的支持，请用户注意！

新版的XFdtd 7.10增加了新的电路设计仿真工具，自带频域仿真分析功能，用户可以在设计完成后同时进行匹配电路或馈电回路电路的特性分析，然后进一步和FDTD仿真结果结合匹配，透过后处理进一步了解这些电路对稳态仿真结果的影响。

l                      Schematic Editor : XFdtd 7.9.10 新增的电路编辑器，可设计匹配/馈电电路并分析其特性。

l                      支持在电路中添加常见的器件并导入Snp文档或整合现存的XFdtd仿真输出在电路里。

l                      支持切换不同的电路器件运作模式或切换FDTD仿真结果代表的运作模式。

l                      支持透过后处理的方式将电路与仿真结果结合，进一步的观察电路对系统的影响。

 

Plot Far Zone Statistics

7.9.10版的XFdtd支持Plot Far Zone Statis·tics 这个macro，用户可以透过代理索取，这个macro可以用来绘图并列显示多个不同频点的输出数据，便于用户分析比较仿真输出。
