PEC Sphere - CST2013 MWS Examples

下载CST设计文件

General Description

In this example the RCS calculation of a metallic sphere is presented. A plane wave is incidented and the scattering properties of the structure are of interest.

Structure Generation

The frequency unit is set to gigahertz, the background material is defined as vacuum, and the boundary conditions are set to "expanded open".

The structure is quite easy to construct by defining a sphere consisting of PEC material.

Solver Setup

Due to the requested RCS calculation the excitation is determined as a plane wave and a farfield monitor is defined at a specified frequency. In addition a 3D field monitors will visualize the propagation of the plane wave through the simulation volume.

Post Processing

The farfield information is stored in the folder Farfields in the navigation tree, where the corresponding plot mode has to be chosen to get the visualization of the RCS properties.

The monitored 3D fields can be examined in the folder 2D/3D Results, while the excitation signal of the plane wave is listed in the folder 1D Results.
