    Question about Gunn Diode

    how gunn diode work Hi Thank you for your answer in advance. Our lab has several Gunn diodes and they are all 10-year-old. Recently, I tried to build X-band oscillator in rectangular waveguide. There is nothing on power spectrum analyzer. And I found something difference with the data sheet...

    CST question: Meshing & Slotline port

    cst mesh slotline Hi, I want to LOCALLY increase mesh density of part of my structure. Does anybody know how to set up? Also, does anyone have any experience in simulating a simple slotline? Is there any empirical port size for slotline line? Thx !!

    How to simulate a microstrip antenna array

    microstrip antenna array using ads Hi, You guys say that one can simulate single antenna element, and then claculate array pattern in either IE3D or CST. I have a question. Do these software account for mutual coupling effect between elements, or they just mutiply single element pattern by...

    Can I define zero thickness metalization in CST?

    Re: CST : Metal Thickness Hi, Element7k Thank you for your answering. I am a novice of CST. I am just wondering if using zero thickness metal could help reduce simulation time and give me the similar result to that of nonzero thickness metal case. The metal thickness is not a serious issue in...

    Can I define zero thickness metalization in CST?

    CST : Metal Thickness Hi, :) Thanks a lot in advance. Could I define "zero" thickness metalization in CST? I tried to use "curve", but I can not define the material. Also, I tried to use "Brick" with zero height, but a error message prompted. Thank you !! WH
