    How calculate the simulated capacitance of coaxial

    Please Help me!!!! I don't get the theoretical value of the capacitance with that formule, why??

    Simulation and modelling of koaxial structures

    I simulated a quarter of coaxial because the coaxial allows simmetry boundary condition (perfect H). I want to obtain the capacitance simulated of the coaxial for comparing the results with different mesh operations. Thank's for all.

    calculate capacitance of coaxial step (Urgent please!!)

    Hy, How could obtain the simulated capacitance of the next structure?. Would I have to use the field calculator?, How?. Thank's for all.

    Simulation and modelling of koaxial structures

    Hy, I've tried to simulate the more simple structure of coaxial that appear in the pdf, but the parameters S aren't correct for me. Moreover, I don't Know How to calculate the Capacitance. My design is the next. What's wrong? Thank's for all.

    How calculate the simulated capacitance of coaxial

    How could I calculate the simulated Capacitance of a coaxial with HFSS? I don't want to calculate the theoretical result. I want the capacitance obtained by HFSS (Approximated). Thank's for all and Regards.

    I want to get an infinite cilynder in Z

    hy: I want to get a infinite cylinder in z axis. Is this possible with HFSS?. I have used condition layered impedance in the extreme of the cylinder. I have used master-slave boundary condition and the result in the both cases is the same: I get a correct result in the form (more or less) but...

    I want to simulate a structure 2D

    Hy, I want to simulate a 2D structure but I don't know what simulator could I use. Specifically: I want to analyze the next 2D structure with a simulator: Ring1=metal. (Radium 0.2meter) Ring2=Vacuum(Radium 0.995 meter) Ring3=dielectric(Radium 1meter) with: pemitivity=2...

    Problems with the excitation (again)

    But the problem that I'm trying to resolve is a coaxial to waveguide transition, not waveguide to coaxial transition..the excitation must to be in the rectangles.

    Problems with the excitation (again)

    Hy: I'm a student of telecomunications thar are using HFSS in her project. I would like to know why the results (like parameters S11 and S21of any structures) depends on length of the integration line using lumped ports. In special, I am Analysing a coaxial to rectangle/ circular waveguide...

    How could I analize this filter ustrip? (URGENT!!!)

    I want to use coaxial with the next model. If I analyze the same filter with waveports (using rectangles with the correct dimensions) the result is correct. But if I use Coaxial (like we can see in the model) the result is wrong. why?. I don't want to change the dimension of the box with a probe...

    [error] Adaptive solution setup, process abc3d : subprocess

    what's the meaning of this error? Thanks.

    How could I analize this filter ustrip?

    I have analized this structure with wave port using rectangles and the result is correct. Now, I want to analize the same structure with coaxial. How can I do it? Note: I show the design with the coaxial. The result is wrong. I want to know how I can obtain a correct result.
