A reply to myself:
For curved structure, I couldn't find a way to expend the curve as a true curve.
However, a comprise that works for me is I instead specify the segment number, and set it to resonably high.
This is OK as at the end from AutoCAD I will also be doing the same to generate a...
Hi,
I have got some resonator drawn in HFSS, and would like to export them to AutoCAD.
I did it using the export, as dwg, and in AutoCAD I was able to import and everything seems to work, until I realized the curve I see in AutoCAD was very blocky, the bends were not smooth at all.
Is there a...
Hi,
I am simulating to find the resonance frequency and measured quality factor of some CPW transmission line resonator with a short circuit as termination.
They are coupled to the feedline via a series coupling capacitor.
I set the length from the coupling cap to the short-to-GND, then I...
Hello,
I am using Driven Terminal for my simulation with some 50Ohm CPW waveguide.
On getting the results, I want to simulate for the given power in dBm, how much current I will end up running through some sections.
However in Driven Terminal the excitation is in terms of incident voltage.
May...
Hello again,
May I know more about the method you are describing?
I was originally confusing it with de-embedding the two feeding lines in series with the ICAP,
however a later revisit to this thread, I realized that you were talking about CPW line with length of ICAP, may I know how exactly it...
Hello,
Thanks a lot for your reply,
I was able to de-embed using an internal function which can be set at the excitation.
Lately I am following another HFSS simulation regarding a parallel plate capacitor, which I think might be a better starting point.
They were using just 2 pieces of metal...
Hello,
I am trying to extract the capacitance of an interdigitated capacitor along a CPW waveguide.
I have been trying different ways, from using Y-parameter by modelling the the thing as a pi-network, however I didn't get something reasonable with the calculated capacitance being heavily...
I am pretty frustrated, though I am not quite confident with the expression, in which I call the surface, take a dot product of the vec_H with the normal to that surface, and then integrate the dot product over that surface, I am getting a fluctuation like below, while I expected an exponential...
Thanks a lot, in fact I am getting numbers pretty close to the expected, however the thing bothered me is when I tried to plot the flux normal to the square, I get fluctuating values, instead of the exponential decay of field I expected.
However from the vector plot, I do see the arrow...
Sorry if this is a duplicated question, but I am working on this and hope to extract the data within this week, after some tries I decided it maybe better to seek advice.
It's actually the same simulation I was running in a previous question:

Thanks a lot for your advice.
Yesterday I tried to define an extra structure, that is a ring surrounding the square hollow and sized within the strip line,
then I refine the mesh only within that ring, and it worked pretty well in greatly reducing the resource needed while keeping a good...
Hi,
I have been simulating some CPW waveguides, and with a small dimension like 13um wide of the center lines and 7um gap, then I have a small square hollow within the (blue) CPW center line as 4x10um.
I wanted to simulate the H field being coupled through that square by the red CPW line...
Hello,
I have been trying to characterise some IDCs using HFSS, but I haven't got any luck confirming my results, in a way that I don't understand which is the correct way to extract the capacitance.
What I have been doing is to draw a layout mentioned on a paper with the dimension and circuit...
