Hi, I am facing problem in finding the input impedance of a unit cell FSS in cst with FSS unit cell template. BY applying unit cell boundary conditions and floquet ports and then simulating with frequency domain solver, I get the S parameters but the input impedance is not calculated. BY simulating simultaneously with floquet ports and (...)
Hi guys! I am here new like in a field of EM simulations. I started to use cst software for simulation microstrip patch antenna @ 5.8 GHz, feed with coaxial probe. I am interested which of the above mentioned solvers are better in sense of accuracy (which will give better matching with measured results of S11 parameter)? In addition if you have
hello friends i want to simulate 2 layer pcb and calculate s parameters. this 2 layer pcb have complex structure . in cst micro wave studio with frequency domain solver its have too long time for simulating and not appropriate . can any one help me to reduce thats needed time for simulation ? :cry::cry:
It means your port is not setup correctly. I've not run (or had access to) cst in a couple months.
Dear all, I am trying to simulate a SOI waveguide in cst MWS using time domain solver with dimensions of silicon (220 nm thickn and 500 nm wide)on top of silica.I try to simulate it for frequency range(192-200 THZ). 130601 I am not getting the expected result.What should be the boundary conditions and other settings for
Hello everyone, I am new to cst just few days back learned it to design and simulate the GPS antenna. The antenna which is already implemented in one of the IEEE paper but for my project work i am doing it. My antenna is "Stacked Patched" type with "Reactive Impedance Surface" on the most bottom substrate. I am using Coaxia
Maybe you are using the older version of your file in the newer installation of cst. Maybe first delete all results then try simulation.
Dear all, Can anyone show me that how to plot antenna gain vs. frequency when using cst frequency domain solver? When using cst time domain solver, I have plotted antenna gain vs. frequency based on broadband monitors. However, cst does not support (...)
hey , im simulating a Helix antenna but i have some Problems the Simulation with cst dont fit the measurements i made . i uploaded some results and some pics . will be happy about any help thx
Hello, I am working with cst 2014 and I am trying to simulate a rectangular lens coupled to a rectangular horn antenna with a little angle of flange in E Plane and a wider angle in H plane (close looking to a H-sectoral antenna) but the meshing in the aperture and in the lens is very dense, due to the little angle of flaring in E plane. The thin
hi everybody. I am simulating an antenna in cst software with frequency domain solver. my frequency range is 0.7 GHz- 2.4 GHz. the result is good. my problem is step frequency. cst give me the result with step frequency of 0.002 GHz but i need to know what exactly is (...)
Hey! I need help for EM Studio. I try to explain it with an easy example. I want set in Low frequency domain solver a current Port on the one side of a cylinder and then show the voltage in this cylinder. How i can set the Voltage Monitor? I find anywere this Option with Low frequency domain Solver. I It would be (...)
Hi to everyone I have a question that troubles me a lot and would be grateful if I could get a little help. I've designed a simple square patch antenna at 60GHz in cst (attached), frequency domain. The problem that I face is that I can't get the maximum gain at broadside. maximum is tilted by 30 degrees. I changed dimensions of the (...)
I have a problem with the simulation of graphene "using cst microwave studio" . graphene is a 2D material and I used the popular approximation of 3D graphene method with a very thin thickness about 1 nm then calculate the relative permittivity εr =106272 . I defined a new material "graphene" by inserted the calcula
Hi Could anyone explain to me the concept and significance of mesh density as a function of steps per wavelength? I am asking this in context of a frequency domain EM-solver - cst MWS. May I ask what are the "steps" and what is the "wavelength" ? I am trying to simulate a Photonic Crystal (silicon pillars in vacuum) within a (...)
The problem appears in cst 2009.But it doesn't appear in cst2006. That's why?
Hi everyone! I would appreciate it if you guys can help me out... I'm new to cst and i'm having a problem in setting my desired frequency bandwidth of the input signal. I want the excitation signal to be a gaussian modulated signal (actually the default excitation) within the bandwidth of 25 ghz up to 35 ghz (in order to have a wideband signal)
Hello everyone, May I know can I do a simulation using cst for ESD simulation in frequency domain to generate E and H fields? Thank you. rgds, leekyg
Greetings, I am trying to model for the first time, so I tried to simulate the standard model form the paper Robinson et al, Analytical formulation for shielding with apertures. To test the Electric fields with probes inside the shielding box I ran the frequency domain solver in cst MWS. How do I get finer results that match the (...)
Hi ! I am new to cst MWS and I want to analyze a periodic structure, I use the unit cell as boundary conditions, so the software puts automatically Floquet ports. But the "Set excitation" line in the "QuickStart Guide" does not get checked. I then run the frequency domain solver and get results that are ok. The only way to get the (...)
