First, open boundary conditions must be defined at the direction of incidence. When exciting with a plane wave, several conditions must be satisfied. Note: In case of plane wave excitation onto an infinite periodic structure, the unit cell approach is recommended which is accessible via the boundary dialog. When exciting with a plane wave, several conditions must be satisfied which will be discussed in the following section. ![]() ![]() The phase reference location of the plane wave excitation is the origin of the global WCS (0,0,0). Please note that the input signal of an excited plane wave is normalized due to the user-defined value of the electric field vector (unit: V/m). In combination with farfield monitors, the radar cross section (RCS) of a scatterer may be calculated. The plane wave excitation source provides you the opportunity to simulate an incident wave from a source located a large distance from the observed object. ContentsįSM export as NFS nearfield scan data exchange format Nearfield sources allow for the excitation of the time domain solver, the integral equation solver and the asymptotic solver by nearfield data described in various formats. Farfield sources allow for the excitation of the integral equation solver and the asymptotic solver by data exported in a farfield source file by CST Microwave Studio. Field Source Overview Field Source Overview Several types of field sources are available for imprint in CST Microwave Studio: Plane wave sources allow for the efficient excitation of linear, circular or elliptical plane waves at the boundary of the calculation domain. ![]()
