You could also apply a "finite conductivity" boundary and set the properties to be that of copper.
Hello everyone, I need to assign a surface impedance boundary condition instead of assigning a finite conductivity to a material with a finite thickness. Does anyone know how to do this? Tks in adv.
Using finite conductivity boundary condition to simulate a thin layer of copper and PEC individually for a transmission line without applying any thickness due to the small skin depth. I realized that the mesh on the PEC one is much much more and of cause smaller than the copper one. Would some one explain why? Thanks!!
Hello, Is there anyone know what is the difference of perfect E, perfect H, and finite conductivity? And when we must use it? or say which is more accurate ? THanks
1) Yes. Assigning a finite conductivity boundary enables u to evaluate the output resistance. 2) You can assign a lumped element at the port of the second coil and observe the current flowing through it. Then the power absorbed by the load resistance can be calculated straightforward. The current through the second coil can be deduced by an (...)
Hi everyone, I read a paragraph in HFSS online help and I am not quite understand it. Just post and see if there anyone has some understand towards this one. It is under keyword "Solving inside or on the Surface" HFSS implicityly places a finite counductivity boundary condition on the surfaces of an object that should not be solved inside
At high frequency like 60 GHz, the conductor thickness is really comparable to the skin depth. In such case, you'd better use 3D metal model and check the solve inside option. To save time, you can also try the finite conductivity boundary with regular sheet metal model, but pay attention to the thickness setup.
How you set the thickness of the conductor when using the "finite conductivity" boundary? Though "solve inside" option used to turn out larger resistance than sheet metal model, you need to pay attention to the thickness setup.
the magic tee designs on which faces the finite conductivity (boundary condition) is applied. 2.Where we have apply the symmetry condition along with the top face of the modal of magic tee?
you could assign this for perfect e ,impedance or finite conductivity for doing this you should click infinite ground plane when you assign this tree boundary .
The most important information for me to capture is the RF resistance of the copper. If "Solve Inside" is not set, will I be missing this data? You do not need to check "Solve Inside" to take into account ohmic losses. Just define material properties or assign "finite conductivity" as outer boundary condition. Check t
I want to simulate spiral inductor , but I don't know how to set boundary condition. 1.if I draw a air box to surround my object , how big the size I should draw ? is the size related to wavelength ? 2.when should I set perfect E,perfect H, finite conductivity , Radiation to be boundary condtion ? I am so confused (...)
Because the conductivity for PEC is infinity, you can't have a finite value of electric field at the boundary, otherwise singularity arises.
Has anyone ever simulated a patch antenna with an ITO (indium-tin-oxide) glass subtrate with HFSS? I tried setting the boundary of the patch and ground as "finite conductivity", "layered impedance" or "impedance" but everytime I have a gain whose value is about 0 dBi. I would appreciate if you can share you experience or tell me how to set (...)
For a single connector simulation using HFSS, please direct me if you have any comments on it: Please kindly download my file and check any part of it has error! 1. For a practical case, do I need to setup a definite thickness of the outer shield cylinder with finite conductivity? 2. Do i need to setup a box for (...)
