    THE FDTD PROGRAMMING GUIDE (beta)

    It is a great work you give us a guide. I am a FDTD fan but till now I didn't resolve how to quickly generate the mesh of the whole simulation area. I try to find the codes, sample or papers. Just three or five papers simply describe the mesh method. It seems that the mesh method is a very...

    how to simulate the crystal under the EM field?

    Now, I have a MZ modulator used as a electric field sensor. That means when the MZ modulator is in the EM field, the laster throug the MZ modulator will be modulated and the output power will change with the amplitude of the EM field. Therefore, I want to design the waveguide of the MZ...

    Simulation of the reverberation chamber using the CST MWS

    Hi, I am simulating the 3D reverberation chamber using MWS. The chamber is like a resonator. So the simulation time s very long. My question, if I want to simulate the behavour of the resonator, how to set the parameters so as to reduce the simulation time? Thank you.

    How to mesh the object in FDTD?

    Hi, I am learning the FDTD and I want to automative mesh the object. But just few papers and books mentioned the method of mesh generator. Does any one has the codes or has the detailed reference paper? Thank you all.

    Help! The CST discrete port

    Here is the picture. The LPDA is located in a reverberation room. The LPDA is perfect conductor. I want to simulate the electric field distribution in the room under the different location of the antenna. I just rotate the antenna. On the most location, the simulation can be done. but on some...

    Help! The CST discrete port

    Hello, everyone. In present, I meet aproblem about the discrete port in CST MWS. The object is perfect conductor. When I set the discrete port on my model. I use the tool on the toolbar to select the middle points of two edge and then set the port on this two points. The discrete port will be...

    How to understand the high-mode in TEM cell?

    Hi, I measured the probe in a TEM cell. The highest frequency of the Cell is 300MHz. It is said when the frequency is larger than 300MHz, there will exist high-mode. So how to understand the high-mode? Does the high-mode correspond to the different frequency?
