Chapter 2-Simulation Workflow
The following example shows a fairly simple Sparameter calculation of a coaxial
connector. Studying this example carefully will help you become familiar with many standard
operations that are important when performing a high frequency simulation with CST STUdIO
SUITE
以下示例显示了同轴连接器相当简单的 Sparameter计算。仔细研究该示例将有助于您熟悉许多标准操作,
这些操作在使用 CSTSTUDIO SUITE执行高频模拟时非常重要。
Go through the following explanations carefully, even if you are not planning to use the software
for Sparameter computations. Only a small portion of the example is specific to this particular
application type while most of the considerations are general to all solvers and applications.
仔细阅读以下解释,即使您不打算使用软件进行 Sparameter计算。该示例中只有一小部分是特定于这种
特定的应用程序类型的,而大多数考虑因素对所有解算器和应用程序都是通用的。
In subsequent sections you will find some remarks concerning how typical procedures may differ
for other kinds of simulations
在接下来的章节中,你会发现一些关于其他类型的模拟的典型程序可能有什么不同的评论。
launch a particular command. Whenever available, the corresponding ribbon item will be displayed
next to the command description. Because of the limited space in this manual, the shortest way to
activate a particular command (i.e. by activating the command from the context menu) is
omitted. You should regularly open the context menu by clicking the right mouse button, to check
available commands for the currently active mode

The Structure
结构
In this example you will model a simple coaxial bend with a tuning stub. You will then calculate the
broadband S-parameter matrix for this structure before looking at the electromagnetic fields inside
this structure at various frequencies. The picture below shows the current structure of interest (it has
been sliced open to aid visualization), and was produced using the pov export option
在夲例中,您将模拟一个带有调谐短截线的简单同轴弯曲。然后,您将计算该结构的宽带S参数矩阵,
然后查看该结构内部不同频率的电磁场。下图显示了当前感兴趣的结构(它巳被切开以帮助可视化),并且
是使用视点导出选项生成的。
construct this structure efficiently. Due to the outer conductor of the coaxial cable the
高效地构建这个结构。由于同轴电缆的外部导体

structure is sealed as if it were embedded in a perfect electric conducting block(apart, of course,
from the ports). For simplification, you can thus model the problem without the outer conductor and
instead embed just the dielectric and inner conductor in a perfectly conducting block.
结构被密封,就好像它被嵌入一个完美的导电块(当然,与端口分开)。为了简化,您可以在没有外部导体
的情况下对问题进行建模,而是将电介质和内部导体嵌入到一个完美的导电块中
In order to simplify this procedure CST MICROWAVE STUDIO allows you to define the
properties of the background material. Any part of the simulation volume that you do not
specifically fill with some material will automatically be filled with the background material For
this structure it is sufficient to model the dielectric parts and define the background material as a
perfect electric conductor.
为了简化这个过程,CST微波工作室允许您定义背景材料的属性。模拟体积的任何部分,如果没有特别
填充某些材料,将自动填充背景材料。对于这种结构,只需对电介质部件进行建模,并将背景材料定乂
为完美的电导体即可。
The method of constructing the structure should therefore be as follows
因此,构造该结构的方法应该如下:
1.2
Model the dielectric (air) cylinders
模扒电介质(空气)圆柱体
Model the inner conductor inside the dielectric part
模拟电介质部件内部的内部导体。

After launching the CST STUDIO SUITE you will enter the start screen showing you a list of
recently opened projects and allowing you to specify the application type which best suits your
requirements. The easiest way to get started is to configure a project template which defines the
basic settings that are meaningful for your typical application. Therefore click on the button in the
section
启动 CST STUDIO SUITE后,您将进入开始屏幕,显示最近打开的项目列表,并允许您指定最适合您
需求的应用程序类型。最简单的方法是配置一个项目模板,它定义了对您的典型应用程序有意义的基本
设置。因此,单击该部分中的按钮。
